God is honest and straightforward, he knows what is supposed to be entitled to those who serve him and those who turn their backs on him. Inorder words, he knows his people. People, especially Christian try doing things which they think it pleases God by going to church, worshipping and giving him praises. Yes that is fine and great but Gods recognize his people from a congregation.To please God, it must come from your heart and soul.
Pleasing God does not necessarily mean going to church i don't say we should not go to church but we should prepare our minds for God. What I am trying to say is that we should ask him for forgiveness of sins because that is the key. Without this, it would just be as if someone is fetching water into a container that has broken at a particular place and this would cause it to leak. After asking for forgiveness of sins we should then go into his ways by worshipping him, studying his words and also attending churches. What I am trying to say in a brief is that the only thing that pleases God most his going through his ways.
