Prayer allows us to worship and praise the Lord. It also allows us to offer confession of our sins, which should lead to our genuine repentance. Moreover, prayer grants us the opportunity to present our requests to God. All of these aspects of prayer involve communication with our Creator. He is personal, cares for us, and wants to commune with us through prayer.
Prayer is central and crucial in the life of the Christian
The neglect of prayer is a major cause of stagnation in the Christian life. Consider the example of Peter in Luke 22:39–62. Jesus went to the Mount of Olives to pray, as was His custom, and told His disciples, "Pray that you may not enter into temptation." The disciples fell asleep instead. The next thing Peter did "was try to take on the Roman army with a sword; then he denied Christ. Peter did not pray, and as a result he fell into temptation. What is true of Peter is true of all of us: we fall in private before we ever fall in public.
Is there a right and wrong time for prayer? Isaiah 50:4 talks about the morning as the time when God gives the desire to pray on a daily basis. But other passages give times of prayer during all hours of the day. No part of the day is set apart as more sanctified than another. Jesus prayed in the morning, during the day, and sometimes all night long. There is evidence that He had a time set aside for prayer; however, considering the relationship Jesus had with the Father, we know that communion between them never stopped.
First Thessalonians 5:17 commands us to pray without ceasing. This means that we are to be in a continual state of communion with our Father. Prayer, then, is central and crucial in the life of the Christian.
