Are your prayers trying to bring you closer to God, or are you trying to convince God to accept your plan?
Reflect for a minute on your recent prayers. Have you been asking God to act in a specific way? The next time you pray, don't tell God your plan, just ask for His guidance and quietly wait for directions.
And when you pray, do not heap up empty phrases as the Gentiles do, for they think that they will be heard for their many words. Do not be like them, for your Father knows what you need before you ask him. Pray then like this: "Our Father in heaven, hallowed be your name.
