It is important to understand the dynamics of prayer. God needs us to pray so He can intervene in earthly issues. Although God already determined his actions, He required men and women to intercede for the actions to be manifested. Much like our relationships with our earthly parents, although they know what we need, sometimes they will appreciate being reminded by us. As long as you have received Jesus as your Lord and Saviour, you have a right to call God your Father. God is holy and responds to his name (1 Samuel 2:2, KJV). Remember that when we show appreciation to God, He blesses us with more.
