Matthew 24:24, For false messiahs and false prophets, will appear and perform great signs and wonders to deceive, if possible, even the elect.  How will we know it is false information if we are not familiar with the truth?  And where can we rely on finding the truth? (trick question)

Following one of Jesus' teachings to his disciples, the Olivet Discourse, the disciples ask Jesus to reveal the sign of His return. Jesus does not give one sign but several. At the top of the list, he warns the disciples of deception and follows it up with warnings of false prophets, false miracles, and the warning not to be deceived. Matthew 24:24.

When Jesus sends His disciples out the first time He gives them a warning; Matthew 10:16  “Behold, I send you out as sheep in the midst of wolves. Therefore be wise as serpents and harmless as doves.  Christ's mandate to us that we become "wise as serpents and harmless as doves" implies that we must develop discernment, the ability to detect the spirits that motivate. The gift of discerning the spirits will become increasingly important as we approach the end of this age because deception will be the hallmark of these extremely dangerous times.

We deduce from this last warning that false "Christian" ministers and ministries will have the capability of performing convincing lying wonders and signs. These false ministers will demonstrate power—occult power—for the specific purpose of leading all people astray, including the most sincere believer. Especially those who are not grounded in the truth!

We have a clear warning from the apostle Paul that the battles we face on a daily basis cannot be won by conventional weapons that we can attain from the world. The weapons we must seek should be spiritual, having the power to destroy arguments and every false claim that sets itself up against the knowledge of God and God's Word, II Corinthians 10:3-5, We are human, but we don’t wage war as humans do. 4 We use God’s mighty weapons, not worldly weapons, to knock down the strongholds of human reasoning and to destroy false arguments. 5 We destroy every proud obstacle that keeps people from knowing God. We capture their rebellious thoughts and teach them to obey Christ.

But still, there will be those who do not want to hear the truth. They will flock to those huge mega-churches to hear that soft preaching that tells them what they want to hear! 2 Timothy 4:3-4, For the time will come when people will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear. 4 They will turn their ears away from the truth and turn aside to myths.
