2Th 2:10-12 And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. (11) And for this cause God shall send them strong delusion, that they should believe a lie: (12) That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
Joh 6:64-68 But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who should betray him. (65) And he said, Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father. (66) From that time many of his disciples went back, and walked no more with him. (67) Then said Jesus unto the twelve, Will ye also go away? (68) Then Simon Peter answered him, Lord, to whom shall we go? thou hast the words of eternal life.
2 Cor 4:1-4 Therefore seeing we have this ministry, as we have received mercy, we faint not; (2) But have renounced the hidden things of dishonesty, not walking in craftiness, nor handling the word of God deceitfully; but by manifestation of the truth commending ourselves to every man's conscience in the sight of God. (3) But if our gospel be hid, it is hid to them that are lost: (4) In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.
John 12:48 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.
Gal 1:6-10 I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel: (7) Which is not another; but there be some that trouble you, and would pervert the gospel of Christ. (8) But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. (9) As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed. (10) 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.
Jude 1:3-5 Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints. (4) For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ. (5) I will therefore put you in remembrance, though ye once knew this, how that the Lord, having saved the people out of the land of Egypt, afterward destroyed them that believed not.
Mar 16:15 And he said unto them, Go ye into all the world, and preach the gospel to every creature.
2Tim 1:13 Hold fast the form of sound words, which thou hast heard of me, in faith and love which is in Christ Jesus.
