"See to it that no one misleads you." It's the warning that Jesus gave concerning the time before His return. We are to guard against the deception of those days. There will be one person in particular who will be exceedingly deceptive, the false prophet.
"And then that lawless one will be revealed. . . The one whose coming is in accord with the activity of Satan, with all power and signs and false wonders, and with all the deception of wickedness for those who perish." 2 Thessalonians 2:8a,9,10a
God has revealed ahead of time what those days will be like so that we can be ready. These pages were written with that objective in mind.
