As a Christian believer we must lean on the word of God. Jesus begins with a sobering warning: Do not allow yourself to be deceived! Many people are familiar with Jesus Christ's Olivet Prophecy.

”. . . Satan himself transforms himself into an angel of light. Therefore it is no great thing if his ministers also transform themselves into ministers of righteousness, whose end will be according to their works” (2 Corinthians 11:14-15). But I fear, lest somehow, as the serpent deceived Eve by his craftiness, so your minds may be corrupted from the simplicity that is in Christ. For if he who comes preaches another Jesus whom we have not preached, or if you receive a different spirit which you have not received, or a different gospel which you have not accepted—you may well put up with it!” (2 Corinthians 11:3-4).
