There have always been false prophets – men and women who claim to speak for and in the name of God but whose priority is themselves. The credential of a true prophet comes from the Torah:
Deuteronomy 18: 18-20
I will raise up for them a prophet like you from among their fellow Israelites, and I will put my words in his mouth. He will tell them everything I command him. I myself will call to account anyone who does not listen to my words that the prophet speaks in my name. But a prophet who presumes to speak in my name anything I have not commanded, or a prophet who speaks in the name of other gods, is to be put to death.”
You may say to yourselves, “How can we know when a message has not been spoken by the Lord?” If what a prophet proclaims in the name of the Lord does not take place or come true, that is a message the Lord has not spoken. That prophet has spoken presumptuously, so do not be alarmed.
The Lord gave Jeremiah a difficult warning to bring to Zedekiah king of Judah; submit to the king of Babylon. It made no sense to Zedekiah. Why would submitting to another king be the way to save his land and his people?
Instead, Zedekiah called for his prophets who told the king what he wanted to hear. So Zedekiah listened to the false prophets and disaster followed! (Jeremiah 27)
Yeshua warned that there will come a false prophet who will be the spokesperson for the coming false messiah. This false prophet will lure the unsuspecting away from God’s truth and ultimately demand the world worship that false messiah. Those who do will lose their lives in God’s final judgement.
PRAY FOR MORE DISCERNMENT AND UNDERSTANDING SO NOT BE DECEIVED.
