This comes across as we start to read the surrounding passages containing Jesus’ above promises. So in the Luke passage Jesus talks about the need to pray to God as our Father (verses 2 and 13), and in John about prayers being made in the context of a relationship with Jesus whose closeness is that of a vine with a branch.
Asking God for things, for help etc. therefore takes on a different dimension. God has a face, so to speak, and is a real person (the most real of persons) rather than a slot machine or an anonymous servant. Moreover in relating to Him as such we find that it no longer becomes just a case of asking Him for something we need, but wondering if He has a take on what we are requesting. This is why Jesus interposes the notion of God’s will being done, and His Kingdom coming as in the Lord’s prayer. Both are meant as necessary reminders that there is a bigger picture and our praying is a means of involving us in it’s painting.
