Prayer is asking God to do what he has already promised to do in His word.  We see this interaction with God evidenced throughout the Bible as his people continued to ask him to follow through on his promises to bring about his kingdom and rule. It’s our right to bring our petitions to the Heavenly Father as adopted sons and daughters through Jesus Christ.  We can be confident that God will answer our prayer because he is faithful to perform his word to bring his purposes to pass for his glory, for our forgiveness, for our own knowledge of God, for godly wisdom, for the strength to obey, and for the gospel to spread.
