'Father' in the Bible

Grace to you and peace [inner calm and spiritual well-being] from God our Father and the Lord Jesus Christ.

and that every tongue will confess and openly acknowledge that Jesus Christ is Lord (sovereign God), to the glory of God the Father.

But you know of Timothy’s tested worth and his proven character, that he has served with me to advance the gospel like a son serving with his father.

To our God and Father be the glory forever and ever. Amen.
