There is a saying that if you want something from someone, you have to let them know that you think they are good looking. If you don’t view them as attractive, the chances of them being willing to give you what you need diminishes.
The Lord God Almighty needs to know the positive attributes you ascribe to him, and he needs to hear those attributes stated repeatedly. He does not need you to be insincere. However, when you focus on the positive attributes of God, you are far less likely to be focused on self, even when you are praying about a personal need. Begin each prayer by focusing on God’s positive attributes, and end each prayer in the same manner.
