& How to decipher amongst what’s offered according to the council of God? John 12:35-50 KJV

[35] Then Jesus said unto them, Yet a little while is the light with you. Walk while ye have the light, lest darkness come upon you: for he that walketh in darkness knoweth not whither he goeth. [36] While ye have light, believe in the light, that ye may be the children of light. These things spake Jesus, and departed, and did hide himself from them. [37] But though he had done so many miracles before them, yet they believed not on him: [38] That the saying of Esaias the prophet might be fulfilled, which he spake, Lord, who hath believed our report? and to whom hath the arm of the Lord been revealed? [39] Therefore they could not believe, because that Esaias said again, [40] He hath blinded their eyes, and hardened their heart; that they should not see with their eyes, nor understand with their heart, and be converted, and I should heal them. [41] These things said Esaias, when he saw his glory, and spake of him. [42] Nevertheless among the chief rulers also many believed on him; but because of the Pharisees they did not confess him, lest they should be put out of the synagogue: [43] For they loved the praise of men more than the praise of God. [44] Jesus cried and said, He that believeth on me, believeth not on me, but on him that sent me. [45] And he that seeth me seeth him that sent me. [46] I am come a light into the world, that whosoever believeth on me should not abide in darkness. [47] 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. [48] 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. [49] For I have not spoken of myself; but the Father which sent me, he gave me a commandment, what I should say, and what I should speak. [50] And I know that his commandment is life everlasting: whatsoever I speak therefore, even as the Father said unto me, so I speak.

Isaiah 2:22 KJV

[22] Cease ye from man, whose breath is in his nostrils: for wherein is he to be accounted of?

For do I now persuade men, or God? or do I seek to please men? for if I yet pleased men, I should not be the servant of Christ. But I certify you, brethren, that the gospel which was preached of me is not after man. For I neither received it of man, neither was I taught it, but by the revelation of Jesus Christ.

Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ. For in him dwelleth all the fulness of the Godhead bodily. And ye are complete in him, which is the head of all principality and power: In whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ: Buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead. And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses; Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross; And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.

Give us help from trouble: for vain is the help of man.
