By their fruit ye shall know them!
Matt. 7: 16-20
16 Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?
17 Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.
18 A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.
19 Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.
20 Wherefore by their fruits ye shall know them.
The opposition MO is to divide and conqueror.
Man needs to listen to the Lord and search the scriptures this is where truth lies and the Holy Spirit will bear witness to all that is of our Lord.
John 5: 39
39 ¶ Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.
Acts 17: 11
11 These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so.
I say these things in the name of Jesus Christ, amen!
SOME folks don't understand that scripture works BOTH ways, and SOME fruity folks think they are exempt from answering for THEIR own rotten fruit.
"When you point at someone, there are four fingers pointing back at you".
I say these things in the name of "he who laughs last laughs best."!
You raised two more of the Scriptural tests for False Prophets, the Berean test and also the good tree/bad tree fruit test of Matthew 7:
And from anyone who claims to be a prophet, we should see all of the fruits of the Spirit. If he claims to be speaking for God but what we see in looking at his life or words is hatefulness, dissatisfaction or sadness, anxiety, meanness, pride, roughness, impulsiveness, etc. - he is to be ignored.
Immediately following the good tree/bad tree test, is Christ's warning that good intentions, good works and claims of authority will not do:
To know Christ we must abide in Him and He in us. Without Him we can "do" nothing (emphasis mine:)
[There is] therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit. For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death. For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit. For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit. For to be carnally minded [is] death; but to be spiritually minded [is] life and peace. Because the carnal mind [is] enmity against God: for it is not subject to the law of God, neither indeed can be. So then they that are in the flesh cannot please God.
But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. if any man have not the Spirit of Christ, he is none of his. - Romans 8:1-9
The answer to every question should begin and end with His Name.
To God be the glory!
