But I am afraid that as the serpent deceived Eve by his cunning, your thoughts will be led astray from a sincere and pure devotion to Christ. -- 2 Corinthians 11:3
So Jesus answered them, “My teaching is not mine, but his who sent me. If anyone's will is to do God's will, he will know whether the teaching is from God or whether I am speaking on my own authority. The one who speaks on his own authority seeks his own glory, but the one who seeks the glory of him who sent him is true, and in him there is no falsehood (John 7:16-18).
