Matthew 24:25

Told you before. The warning against the delusions of the last days was given so that Christians might have an intelligent understanding of the dangers that would confront them, that they might be alert to these dangers, that they might recognize the false christs and the false prophets for what they are, and thus not be deceived (see John 13:19; 14:29; 16:4). The fact that all these things have been clearly set forth by Inspiration constitutes the best possible reason why “the elect” should be diligent in their study of all that God has revealed concerning the delusions of the last days.
