Note 1 at Lu 11:1: When you consider that Jesus was the greatest miracle worker who had ever walked the earth and the greatest preacher who had ever lived (Mt 7:28-29, Mr 1:22, and Lu 4:32), it is amazing that His disciples asked Him to teach them to pray. Why didn't they ask Him to teach them how to work these miracles or how to preach like Him and amaze the people with their doctrine?

It's because Jesus' prayer life was even more powerful than His miracles or His doctrine (see note 1 at Mr 1:35). Indeed, it was His union with the Father that gave Him His power to work miracles and His authority to speak as no man had ever spoken before (Joh 7:46). Jesus said repeatedly that it was His Father who was doing the miracles through Him (Joh 5:19-20, 30; and 14:10) and that His doctrine was not His own but the Father's (Joh 7:16, 8:28, 12:49, and 14:10).

The same holds true today. Jesus said to us in Joh 15:5 that without Him, we can do nothing. There are many things that we should do in addition to prayer, but there is nothing that we can effectively do without prayer. Prayer is one of the main ways of abiding in Him (Joh 15:7). Therefore, our request should be like these disciples'--"Lord, teach us to pray."
