God teaches us in his word that the human heart is deceitful above all things:
“The heart is deceitful above all things, and desperately sick; who can understand it?” Jeremiah 17:9
God also teaches us that faith comes not from our mind or heart but by hearing the Word of God:
“How then will they call on him in whom they have not believed? And how are they to believe in him of whom they have never heard? And how are they to hear without someone preaching? And how are they to preach unless they are sent? As it is written, “How beautiful are the feet of those who preach the good news!” But they have not all obeyed the gospel. For Isaiah says, “Lord, who has believed what he has heard from us?” So faith comes from hearing, and hearing through the word of Christ.” Romans 10:14-17
However, America’s Joel “What-big-shiny-teeth-you-have” Osteen, teaches the exact opposite to God’s Word. In fact, he encourages people to turn off their brains off and follow their wicked hearts.
“Faith is not in your head. Faith is in your heart. Sometimes you have to turn your mind off and listen to your heart.”
