Although the Lord’s Prayer is clearly Christian in origin and, I would guess, exclusively Christian in usage, actually there is nothing in that could not be sincerely prayed by Jews. And yet, a closer look reveals just how Christian the prayer is. We call God “Father” because we his children in the Son. The coming kingdom is the one preached by Jesus. Our daily bread includes the bread of the Eucharist. Even “the time of trial” points to the travails of the end when Christ-believers might find themselves denying him. In this way, the prayer both enables and expresses our being “joint heirs with Christ” (Romans 8:17). Rather than a set of words, it is really a way of praying.
God, teach us to be your children in Jesus both in name and in reality. Amen.
