Jude’s Alert

“For certain men have crept in among you unnoticed—ungodly ones who were designated long ago for condemnation. They turn the grace of our God into a license for immorality, and they deny our only Master and Lord, Jesus Christ.” (Jude 1:4)

Early Warnings in the Law and Prophets

• Deuteronomy 13:1-4 — “If a prophet or dreamer of dreams arises among you and proclaims a sign or wonder to you…and says, ‘Let us follow other gods’…you must not listen…For the LORD your God is testing you to find out whether you love Him with all your heart and with all your soul.”

• Jeremiah 23:16 — “Do not listen to the words of the prophets who prophesy to you. They fill you with false hopes; they speak visions from their own minds, not from the mouth of the LORD.”

• Isaiah 9:15-16 — “…the prophet who teaches lies is the tail. Those who guide this people mislead them, and those who are guided are led astray.”

Jesus Warns His Disciples

• Matthew 7:15-16 — “Beware of false prophets. They come to you in sheep’s clothing, but inwardly they are ravenous wolves. By their fruit you will recognize them.”

• Matthew 24:11, 24 — “Many false prophets will arise and mislead many…For false christs and false prophets will appear and perform great signs and wonders that would deceive even the elect, if that were possible.”

• Mark 13:22-23 — “…be on your guard; I have told you everything in advance.”

Paul’s Repeated Cautions

• Acts 20:29-30 — “I know that after my departure, savage wolves will come in among you and will not spare the flock. Even from your own number, men will rise up and distort the truth to draw away disciples after them.”

• 2 Corinthians 11:13-15 — “Such men are false apostles…Satan himself masquerades as an angel of light.”

• Galatians 1:8-9 — “Even if we or an angel from heaven should preach a gospel contrary to the one we preached to you, let him be under a curse!”

• 1 Timothy 4:1-2 — “The Spirit expressly states that in later times some will abandon the faith to follow deceitful spirits and the teachings of demons.”

• 2 Timothy 4:3-4 — “The time will come when men will not tolerate sound doctrine…but will turn their ears away from the truth and turn aside to myths.”

• Titus 1:10-11 — “Many are rebellious and full of empty talk and deception…they undermine entire households and teach things they should not for the sake of dishonest gain.”

Peter Echoes Jude

• 2 Peter 2:1-3 — “Just as there will be false teachers among you…Many will follow in their depravity, and because of them the way of truth will be defamed. In their greed these teachers will exploit you with fabricated words.”

John: Testing the Spirits

• 1 John 4:1 — “Beloved, do not believe every spirit, but test the spirits to see whether they are from God. For many false prophets have gone out into the world.”

• 2 John 7-11 — “Many deceivers have gone out…If anyone comes to you but does not bring this teaching, do not receive him into your home or welcome him.”
