God’s standards for His prophets are strict. The Bible states if the word a self proclaimed prophet speaks “does not take place or come true, that is a message the LORD has not spoken” (Deut. 18:22; see also Jer. 14:14; 23:21, 32; 28:15; Ezek. 13:6). The punishment for speaking falsely in God’s name was death (Deut. 18:20). Nothing has changed during the New Testament era.
Exhibit #1
This video by Chris Roseborough from Fighting for the Faith. In it he contends that the modern charismatic heresies centered on false prophecy and specifically that false prophecy is not a sin, maybe just a mistake. He posits that false prophecy is tantamount to violating Exodus 20:7 “Thou shalt not take the Lord thy God’s name in vain” It is attaching God’s name to a lie.
Exhibit #2
Donnie, from the channel Idiot with a Bible, made this video. He has a friendly and non pretentious skill for explaining theological concepts. He always has contextually sound Biblical teaching.
