'Father' in the Bible

Grace and peace to you from God our Father and the Lord Jesus Christ!

For though you may have ten thousand guardians in Christ, you do not have many fathers, because I became your father in Christ Jesus through the gospel.

yet for us there is one God, the Father, from whom are all things and for whom we live, and one Lord, Jesus Christ, through whom are all things and through whom we live.

Then comes the end, when he hands over the kingdom to God the Father, when he has brought to an end all rule and all authority and power.
