'Father' in the Bible

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

For if you were to have countless tutors in Christ, yet you would not have many fathers, for in Christ Jesus I became your father through the gospel.

yet for us there is but one God, the Father, from whom are all things and we exist for Him; and one Lord, Jesus Christ, by whom are all things, and we exist through Him.

then comes the end, when He hands over the kingdom to the God and Father, when He has abolished all rule and all authority and power.
