Prayer is central to our lives with the Lord. Yet, we can through periods of prayerlessness. One reason we do this is because we forget that prayer is worship. God wants us to be dependent upon Him. Prayer becomes a vehicle of affirmation to this wonderful dependency.
Prayer is also communication.
God never tires of listening to us or looking upon us. As long as we approach Him with a humble heart, He will listen to our needs and burdens. And prayer is not just for our benefit. We see Abraham pleading for Sodom and Gomorrah. In the Wilderness, Moses pleads with the Lord not to destroy Israel for their idolatry and murmuring.
