I have been praying for several days over my part of this discussion and have something prepared to answer the question What is man? from the Christian worldview.
But wouldn't you know I have to go out-of-town for the biggest part of the day, so I won't be able to engage in the actual conversation until later on today.
Anyhow, I decided to go ahead and post what I'm compelled to post.
What is [a Christian] man?
Hes different. He involuntarily perceives things that others cannot. Before he believes in Christ, he is already known to God and has been chosen. Only those who are chosen are able to hear the Word.
Jesus said unto them, If God were your Father, ye would love me: for I proceeded forth and came from God; neither came I of myself, but he sent me. Why do ye not understand my speech? [even] because ye cannot hear my word. John 8:42-43
I am the good shepherd, and know my [sheep], and am known of mine. As the Father knoweth me, even so know I the Father: and I lay down my life for the sheep. And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, [and] one shepherd. Therefore doth my Father love me, because I lay down my life, that I might take it again. - John 10:14-17
I am come a light into the world, that whosoever believeth on me should not abide in darkness. And if any man hear my words, and believe not, I judge him not: for I came not to judge the world, but to save the world. He that rejecteth me, and receiveth not my words, hath one that judgeth him: the word that I have spoken, the same shall judge him in the last day. - John 12:46-48
But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you. Therefore, brethren, we are debtors, not to the flesh, to live after the flesh. For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.
For as many as are led by the Spirit of God, they are the sons of God. For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
The Spirit itself beareth witness with our spirit, that we are the children of God: And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with [him], that we may be also glorified together. Romans 8:9-17
And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge; And to knowledge temperance; and to temperance patience; and to patience godliness; And to godliness brotherly kindness; and to brotherly kindness charity. 2 Peter 1:5-7
And the second [is] like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets. Matthew 22:36-40
He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him. - 1 John 2:4
If we confess our sins, he is faithful and just to forgive us [our] sins, and to cleanse us from all unrighteousness. - 1 John 1:9
If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast [them] into the fire, and they are burned. If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you. Herein is my Father glorified, that ye bear much fruit; so shall ye be my disciples. - John 15:4-8
But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, Meekness, temperance: against such there is no law. - Galatians 5:22-23
But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you; That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust. For if ye love them which love you, what reward have ye? do not even the publicans the same? And if ye salute your brethren only, what do ye more [than others]? do not even the publicans so?
Be ye therefore perfect, even as your Father which is in heaven is perfect. Matthew 5:44-48
There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love. We love him, because he first loved us. 1 John 4:16-19
And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me. Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ's sake: for when I am weak, then am I strong. 2 Corinthians 12:9-10
But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you. Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day [is] the evil thereof. Matthew 6:33-34
Blessed [be] the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead, To an inheritance incorruptible, and undefiled, and that fadeth not away, reserved in heaven for you, Who are kept by the power of God through faith unto salvation ready to be revealed in the last time. Wherein ye greatly rejoice, though now for a season, if need be, ye are in heaviness through manifold temptations: - 1 Peter 1:4-6
In my Father's house are many mansions: if [it were] not [so], I would have told you. I go to prepare a place for you. John 14:2
For unto the angels hath he not put in subjection the world to come, whereof we speak. But one in a certain place testified, saying, What is man, that thou art mindful of him? or the son of man, that thou visitest him? Thou madest him a little lower than the angels; thou crownedst him with glory and honour, and didst set him over the works of thy hands: Thou hast put all things in subjection under his feet. For in that he put all in subjection under him, he left nothing [that is] not put under him. But now we see not yet all things put under him.
But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man. For it became him, for whom [are] all things, and by whom [are] all things, in bringing many sons unto glory, to make the captain of their salvation perfect through sufferings. For both he that sanctifieth and they who are sanctified [are] all of one: for which cause he is not ashamed to call them brethren, Saying, I will declare thy name unto my brethren, in the midst of the church will I sing praise unto thee. And again, I will put my trust in him. And again, Behold I and the children which God hath given me.
Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil; And deliver them who through fear of death were all their lifetime subject to bondage. For verily he took not on [him the nature of] angels; but he took on [him] the seed of Abraham. Hebrews 2:5-16
Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
Therefore whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock: And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock. Matthew 7:22-25
O Timothy, keep that which is committed to thy trust, avoiding profane [and] vain babblings, and oppositions of science falsely so called: Which some professing have erred concerning the faith. Grace [be] with thee. Amen - 1 Timothy 6:20-21
So also [is] the resurrection of the dead. It is sown in corruption; it is raised in incorruption: It is sown in dishonour; it is raised in glory: it is sown in weakness; it is raised in power:
It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body.
And so it is written, The first man Adam was made a living soul; the last Adam [was made] a quickening spirit. Howbeit that [was] not first which is spiritual, but that which is natural; and afterward that which is spiritual. The first man [is] of the earth, earthy: the second man [is] the Lord from heaven.
As [is] the earthy, such [are] they also that are earthy: and as [is] the heavenly, such [are] they also that are heavenly. And as we have borne the image of the earthy, we shall also bear the image of the heavenly. I Corinthians 15:42-48
In either case, the understanding itself may become part of the Christians worldview and thus will constitute a firm boundary which cannot be broached by any non-Spiritual argument to the contrary. In the Christian mans worldview, each core belief is more important than mortal life.
