Clearly came the words: "An apostasy is coming, know the truth." 

Apostasy is generally defined as a falling away, a withdrawal, or a defection. In Christianity apostasy is seen as a withdrawal from faith and trust in God.

Again with clarity came these words: "Do not be taken in by the lies. The apostasy will test the faith and commitment of the masses. Be alert be prepared, but do not be taken in or shaken in your faith."

Strong' Concordance defines apostasy as defection from truth, falling away, or forsake.

In Hebrew the meaning of apostasy is rebellious. 

Jesus tells us in John 8; "You are truly My disciples if you remain faithful to My teachings And you will know the truth and the truth will set you free."

The bible has much to say regarding apostasy. If we are to remain strong in faith, alert, prepared and not be taken in or shaken in our faith we must know His Word. Some verses call it wickedness, others call it iniquities or transgressions.

But El Elyon, God most High calls it apostasy, sin.

"Therefore, beloved, since you already know these things, be on your guard so that you will not be carried away by the error of the lawless and fall from your secure standing. But grow in the grace and knowledge of our Lord and Savior Jesus Christ. To Him be the glory both now and to the day of eternity." 2 Peter 3:17-18
