God is father of all by creation, so that in that sense we can say that all humanity are sons and daughters of God, and that we in that sense are all one family, even as we are one humanity, one race, certainly intermingled, whatever the biological differences may be.
But God is father in the deepest sense to all who put their faith in Jesus:
So in Christ Jesus you are all children of God through faith…
We need God as our Father, and we find that through faith in Jesus. And I believe God seeks as a father the lost throughout the world, everyone whom he has created, since they in that sense are his children. Sadly we rebel and distance ourselves from God in our lostness. But he seeks us out, and longs for our return, even as the father did in Jesus’ story of the lost (“prodigal”) son.
God being our father through faith in Jesus, we are then all one family, brothers and sisters with and in Jesus, who is not ashamed to be identified with us in that way. It is a family thing, a family matter, something in a true sense that ends up being closer and more intimate than our own immediate biological families.
We need God as our Father, I know I do through all the questions and problems of life. And I need the family, all who are in Jesus, brothers and sisters with me in him. A blessing meant not only for us, but for the world.
Our Father in heaven,
hallowed be your name,
your kingdom come,
your will be done,
on earth as it is in heaven.
Give us today our daily bread.
And forgive us our debts,
as we also have forgiven our debtors.
And lead us not into temptation,
but deliver us from the evil one,
for yours is the kingdom and the power and the glory forever. Amen.
