Anyone can talk a good game, but what their life produces reveals what is in their hearts. False teachers almost always live lavish lifestyles, consumed with the things of this world, and attempting to keep one foot on earth and the other in Heaven. This, of course, is not possible (Matthew 6:24; 1 John 2:15-17). What a man says is not a good indicator of who he is. It’s what his life produces for the kingdom that is a good indicator.
Beware of false teachers who attempt to drag you into their deception (Colossians 2:8). They are those who think they know Jesus, but He doesn’t know them (Matthew 7:21–23). Their teaching will leave you even worse off than they are (Matthew 23:15), and no closer to eternity in Christ.
