The greatest pleasure for the Greatest, is to be recognized as the Greatest, by the worship of his creation, the lesser. We worship God for who he is as a person, his character, nature and attributes. We praise God, for the great things he does.
It is called a sacrifice of praise, because you leave your things, and go and do God's things, worshipping him. God does not exist for us, but we exist for him.
