As the disciples saw Him pray and they remembered that none can pray like him, we can understand the disciples in Matthew 6, saying “Lord, teach us to pray”. There is something about the Lord’s prayer that touched them. I wish we had the words that were said, but all we have is what is mentioned in Matthew 6 at this point. When we think about all he is, and has done, and think about Him being our life, we feel confident that if we just ask that He would take us into a closer fellowship with Himself. In that close fellowship we expect Him to teach us to pray as He only can pray.
This is based on some portion from the book With Christ in the School of Prayer by Andrew Murray.
