“Some people are offended that we are taught to address God as Father. The greater offense may be the little word Our.
In this prayer we are taught to pray, not as individuals, but as the
church. When we say ‘Our,’ we are not being possessive. Many a person
has come to grief attempting to domesticate God as a cheerleader for
the American way or as a cosmic Federal Express. We say ‘Our’ because
of the astounding recognition that this God, the one who created the
universe and flung the planets into their courses, the great God of
heaven and earth, has willed to become our God. Before we reach out to
God, God reached out to us and claimed us, promised to be our God,
promised to make us God’s people. Thus, not because of who we are or
what we have done, but rather because of what God in Jesus Christ has
done, we are privileged to say, ‘Our Father.’”
