What do you have to do to please God? First , you must believe that he is God. As a child, you did things that your parents wanted you to do, whether you liked them or not,because it was what pleased them. The things they liked, they wanted you do do, and that pleased them if you did them. To please God is to do the things that pleases him,and the things he like. You can only accomplish this by learning of God. His thoughts, his ways. That is why he told them in the old testament that their ways were not his ways, and their thoughts were not his thoughts. His ways and his thoughts were revealed clearly when he sent his beloved Son , Jesus Christ to teach them to us.
