Unsound Doctrine.
So God will cause them to be greatly deceived, and they will believe these lies. Then they will be condemned for enjoying evil rather than believing the truth.--2 Thessalonians 2:11, 12, NLT
THOSE WHO ARE UNWILLING to accept the plain, cutting truths of the Bible are continually seeking for pleasing fables that will quiet the conscience. The less spiritual, self-denying, and humiliating the doctrines presented, the greater the favor with which they are received. These persons degrade the intellectual powers to serve their carnal desires. Too wise in their own conceit to search the Scriptures with contrition of soul and earnest prayer for divine guidance, they have no shield from delusion. Satan is ready to supply the heart's desire, and he palms off his deceptions in the place of truth.
....All who neglect the word of God to study convenience and policy, that they may not be at variance with the world, will be left to receive damnable heresy for religious truth. Every conceivable form of error will be accepted by those who willfully reject the truth. He who looks with horror upon one deception will readily receive another. The apostle Paul, speaking of a class who "received not the love of truth, that they might be saved," declares: "For this cause God shall send them strong delusion, that they should believe a lie: that they all might be damned who believe not the truth, but had pleasure in unrighteousness." 2 Thessalonians 2:10-12. With such a warning before us it behooved us to be on our guard as to what doctrines we receive.--The Great Controversy, 523.
