In Mark 7 Jesus is talking to the Pharisees and Scribes. He tells them they are worshiping in vain. He says they honor him with their lips but their heart is far from HIM. They follow traditional teaching of doctrines, the way man perceives it. But Jesus makes it clear, that what defiles man comes out of heart.
"Now when ever I am faced with a challenge I don't sit and cry like I used to, I command it to move in the name of Jesus Christ and it surely does. Now I have no doubt that I am more than a conqueror in Christ." - Oforiwaa Boamah
