2Pe 2:1 But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction.
2Ti 4:3 For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears; 4 And they shall turn away [their] ears from the truth, and shall be turned unto fables.
2Corinthians 11:3 But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ. 4 For if he that cometh preacheth another Jesus, whom we have not preached, or [if] ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with [him].

in response to all false and heretical teachings:
Rev_9:2 And he opened the bottomless pit; and there arose a smoke out of the pit, as the smoke of a great furnace; and the sun and the air were darkened by reason of the smoke of the pit.
I believe this verse applies to all and anything else than the true gospel of Jesus Christ.
Madame Blavatsky, Annie Besant, Jiddu Krishnamurti...the Theosophical Society
Satan has its own plan of salvation. He knows the meaning of love and the effects of sin. He knows the world problem is sin. He has his own agenda or 'solution' which he copies from God. The difference is that he cannot dissolve the problem of sin, because if sin is taken out of the way he won't be honored. So all these clever ploys to make the world a better place and just love is actually no solution at all. Why? because even though there are elements of love and humility involved, it all still stems from a dead spirit. The soul is given 'life' but the spirit is in the dark. That's why you need to be reborn...from death to life....from darkness to light.
2Co_11:3 But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ.
