I see where you’re going. Let me address it in this way:
1 Tim. 2:
1 First of all, then, I urge that supplications, prayers, intercessions, and thanksgivings be made for all men,
2 for kings and all who are in high positions, that we may lead a quiet and peaceable life, godly and respectful in every way.
3 This is good, and it is acceptable in the sight of God our Savior,
4 who desires all men to be saved and to come to the knowledge of the truth.
5 For there is one God, and there is one mediator between God and men, the man Christ Jesus,
So Paul instructs us to pray for others. It is good to intercede for others. Therefore Christians can intercede for others. I trust that this is accepted. How about the saints? Can they pray for us in Heaven?
Hebrews 12:1 - Wherefore seeing we also are compassed about with so great A CLOUD OF WITNESSES, let us lay aside every weight, and the sin which doth so easily beset [us], and let us run with patience the race that is set before us.
Do we come only to God or do we also come to the assembly of Saints in heaven as well?
Hebrews 12:22 But YE ARE COME UNTO mount Sion, and unto the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels,
12:23 To the general assembly and CHURCH OF THE FIRSTBORN, which are written in heaven, and to God the Judge of all, AND TO THE SPIRITS OF JUST MEN MADE PERFECT,
12:24 And to Jesus the mediator of the new covenant, and to the blood of sprinkling, and to the sprinkled blood that speaks more graciously than the blood of Abel.
Paul says yes. He says we come directly not only to God, but to an assembly of Saints in heaven (The just men made perfect) exactly in the context of Jesus being the mediator!. Are we supposed to ignore them? The Bible says no!! Jesus is indeed the one and unique mediator. However, it is indeed him as a mediator, that makes all other mediation possible.
Do the saints pray in heaven? The book of Revelation tells us:
5:8 And when he had taken the book, the four beasts and four [and] twenty elders fell down before the Lamb, having every one of them harps, and golden vials full of odours, which are the PRAYERS OF SAINTS.
8:3 And another angel came and stood at the altar, having a golden censer; and there was given unto him much incense, that he should offer [it] with THE PRAYERS OF ALL SAINTS upon the golden altar which was before the throne. 8:4 And the smoke of the incense, [which came] with the PRAYERS OF THE SAINTS, ascended up before God out of the angel’s hand.
Obviously they do pray, and as we saw in Hebrews we come to these saints, who we see intercede for us.
Is there more evidence that the Saints are aware of what is going on at earth, and do they ask for justice?:
Rev 6:9 And when he had opened the fifth seal, I saw under the altar the souls of them that were slain for the word of God, and for the testimony which they held:
6:10 And they cried with a loud voice, saying, How long, O Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth?
18:18 And cried when they saw the smoke of her burning, saying, What [city is] like unto this great city!
18:19 And they cast dust on their heads, and cried, weeping and wailing, saying, Alas, alas, that great city, wherein were made rich all that had ships in the sea by reason of her costliness! for in one hour is she made desolate.
18:20 Rejoice over her, [thou] heaven, and [ye] holy apostles and prophets; for God hath avenged you on her.
So we have further evidence that the Saints in heaven are aware of what is going on in earth, and they specifically pray for things that go on in earth. We must remember that Saints in heaven are not bound by time and space as we are. In eternity, 1 John 3:2 tells us:
Beloved, we are God’s children now; it does not yet appear what we shall be, but we know that when he appears we shall be like him, for we shall see him as he is.
There is only one body, the Church. The church is not one church in heaven as opposed to one church on earth. The one church is intimately connected with each other (remember the image of the vine and the branches in John 15). And those in heaven are just men made perfect. As the body is called to love each other, are the saints in heaven, even though they are aware of what is going on in earth, according to scripture just given, careless as to what is going on in the lives of those on earth? Of course not!!! Christ calls perfected people to love the rest of the body. I can be confident that they will intercede for those on earth. What does it profit? James explains:
James 5:16 The effectual fervent prayer of a righteous man availeth much. Those in heaven are perfectly righteous, and their prayers are efficacious. How can one ignore them? There is one body of Christ, which includes all Christians.
1 Cor. 12:14 For the body is not one member, but many.
12:15 If the foot shall say, Because I am not the hand, I am not of the body; is it therefore not of the body?
12:16 And if the ear shall say, Because I am not the eye, I am not of the body; is it therefore not of the body?
12:17 If the whole body [were] an eye, where [were] the hearing? If the whole [were] hearing, where [were] the smelling?
12:18 But now hath God set the members every one of them in the body, as it hath pleased him.
12:19 And if they were all one member, where [were] the body?
12:20 But now [are they] many members, yet but one body.
12:21 And the eye cannot say unto the hand, I have no need of thee: nor again the head to the feet, I have no need of you.
Again, does a good Christian HAVE to have intercession from the saints in Heaven? No. But it is there for us.
1 Tim. 2:
1 First of all, then, I urge that supplications, prayers, intercessions, and thanksgivings be made for all men, 2 for kings and all who are in high positions, that we may lead a quiet and peaceable life, godly and respectful in every way. 3 This is good, and it is acceptable in the sight of God our Savior, 4 who desires all men to be saved and to come to the knowledge of the truth. 5 For there is one God, and there is one mediator between God and men, the man Christ Jesus, So Paul instructs us to pray for others.
Yes, Paul was speaking to saints who were living on the earth, and not an instruction to invoke angels or the saints who have departed this space/time continuum. You do understand that don't you?
It is good to intercede for others. Therefore Christians can intercede for others. I trust that this is accepted. How about the saints? Can they pray for us in Heaven?
Because saints in heaven can petition God is not all allowance to practice necromancy which God has forbidden.
Hebrews 12:1 - Wherefore seeing we also are compassed about with so great A CLOUD OF WITNESSES, let us lay aside every weight, and the sin which doth so easily beset [us], and let us run with patience the race that is set before us.
Firstly, Hebrews 12:1 is not separate from Hebrews 11, which is where we find the context of 12:1.
Hebrews 11 expounds on the long list of preceeding witnesses who exhibited faith, of which the "Wherefore" points to those witnesses who are recorded in the Scriptures as great people of faith. It is THEY who are the "cloud of witnesses", who stand as witnesses who went before.
Hebrews 11:
Hebrews 11
1 Now faith is the substance of things hoped for, the evidence of things not seen. 2 For by it the elders obtained a good testimony.
3 By faith we understand that the worlds were framed by the word of God, so that the things which are seen were not made of things which are visible.
4 By faith Abel offered to God a more excellent sacrifice than Cain, through which he obtained witness that he was righteous, God testifying of his gifts; and through it he being dead still speaks.
5 By faith Enoch was taken away so that he did not see death, and was not found, because God had taken him;[a] for before he was taken he had this testimony, that he pleased God. 6 But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him. 7 By faith Noah, being divinely warned of things not yet seen, moved with godly fear, prepared an ark for the saving of his household, by which he condemned the world and became heir of the righteousness which is according to faith.
8 By faith Abraham obeyed when he was called to go out to the place which he would receive as an inheritance. And he went out, not knowing where he was going. 9 By faith he dwelt in the land of promise as in a foreign country, dwelling in tents with Isaac and Jacob, the heirs with him of the same promise; 10 for he waited for the city which has foundations, whose builder and maker is God.
11 By faith Sarah herself also received strength to conceive seed, and she bore a child[b] when she was past the age, because she judged Him faithful who had promised. 12 Therefore from one man, and him as good as dead, were born as many as the stars of the sky in multitudeinnumerable as the sand which is by the seashore.
13 These all died in faith, not having received the promises, but having seen them afar off were assured of them,[c] embraced them and confessed that they were strangers and pilgrims on the earth. 14 For those who say such things declare plainly that they seek a homeland. 15 And truly if they had called to mind that country from which they had come out, they would have had opportunity to return. 16 But now they desire a better, that is, a heavenly country. Therefore God is not ashamed to be called their God, for He has prepared a city for them.
17 By faith Abraham, when he was tested, offered up Isaac, and he who had received the promises offered up his only begotten son, 18 of whom it was said, In Isaac your seed shall be called,[d] 19 concluding that God was able to raise him up, even from the dead, from which he also received him in a figurative sense.
20 By faith Isaac blessed Jacob and Esau concerning things to come.
21 By faith Jacob, when he was dying, blessed each of the sons of Joseph, and worshiped, leaning on the top of his staff.
22 By faith Joseph, when he was dying, made mention of the departure of the children of Israel, and gave instructions concerning his bones.
23 By faith Moses, when he was born, was hidden three months by his parents, because they saw he was a beautiful child; and they were not afraid of the kings command.
24 By faith Moses, when he became of age, refused to be called the son of Pharaohs daughter, 25 choosing rather to suffer affliction with the people of God than to enjoy the passing pleasures of sin, 26 esteeming the reproach of Christ greater riches than the treasures in[e] Egypt; for he looked to the reward.
27 By faith he forsook Egypt, not fearing the wrath of the king; for he endured as seeing Him who is invisible. 28 By faith he kept the Passover and the sprinkling of blood, lest he who destroyed the firstborn should touch them. 29 By faith they passed through the Red Sea as by dry land, whereas the Egyptians, attempting to do so, were drowned.
30 By faith the walls of Jericho fell down after they were encircled for seven days. 31 By faith the harlot Rahab did not perish with those who did not believe, when she had received the spies with peace.
32 And what more shall I say? For the time would fail me to tell of Gideon and Barak and Samson and Jephthah, also of David and Samuel and the prophets: 33 who through faith subdued kingdoms, worked righteousness, obtained promises, stopped the mouths of lions, 34 quenched the violence of fire, escaped the edge of the sword, out of weakness were made strong, became valiant in battle, turned to flight the armies of the aliens. 35 Women received their dead raised to life again.
Others were tortured, not accepting deliverance, that they might obtain a better resurrection. 36 Still others had trial of mockings and scourgings, yes, and of chains and imprisonment. 37 They were stoned, they were sawn in two, were tempted,[f] were slain with the sword. They wandered about in sheepskins and goatskins, being destitute, afflicted, tormented 38 of whom the world was not worthy. They wandered in deserts and mountains, in dens and caves of the earth.
39 And all these, having obtained a good testimony through faith, did not receive the promise, 40 God having provided something better for us, that they should not be made perfect apart from us.
Now, verse 11, which cannot be separated from chapter 11, lest you miss the context, and thus the meaning.
1 Therefore we also, since we are surrounded by so great a cloud of witnesses
The "Therefore" is pointing to those witnesses of faith who's faith is a constant reminder, surrounding the heart and mind of the Christian to:
"let us lay aside every weight, and the sin which so easily ensnares us, and let us run with endurance the race that is set before us, 2 looking unto Jesus, the author and finisher of our faith, who for the joy that was set before Him endured the cross, despising the shame, and has sat down at the right hand of the throne of God.
Do we come only to God or do we also come to the assembly of Saints in heaven as well?
Wrong question. First answer this, where in Scripture or the writings of the first three centuries of the Church is there any directive to pray to angels or the spirits of departed saints.
You are confusing the intercession of angels and glorified saints with a directive to initiate contact with them through prayer or any other invocation, both of which are forbid in Scripture.
God has directed angels and glorified saints to intercede for the saints on earth, but that is not a directive nor permission or license to practice necromacy or invoking angels.
They are two very different actions.
