When His disciples asked Him to teach them to pray, Jesus gave them the Model Prayer. He commanded them to pray in that manner continually. The Model Prayer played a role in my life even before my salvation. Several years before I was saved, I attended religious services with some friends on a fairly regular basis on Saturdays. In each service, the highlight for me was when we would sing a somewhat shortened version of the Model Prayer. Although I was not a believer, I always felt something drawing me when I would sing those words.
A few years later, because of my reading some books about the Bible, I was praying the Model Prayer on a regular basis for several weeks even though I was not saved yet. At some point while I was doing so, I was saved.
Since my salvation, I have prayed the Model Prayer in some form nearly every day. Jesus said to pray this way, and we should heed His command.
Several years ago, I produced a handout based on the Model Prayer that compiles many prayers from Scripture that I have used as I pray in that manner. This handout aligns those prayers with the corresponding statements in the Model Prayer.
