'Father' in the Bible

Paul, Silas, and Timothy: To the Church of the Thessalonians which is in God the Father and the Lord Jesus Christ. May grace and peace be granted to you.

For we never fail to remember your works of faith and labours of love and your persistent and unwavering hope in our Lord Jesus Christ in the presence of our God and Father;

For you know that we acted towards every one of you as a father does towards his own children, encouraging and cheering you,

But may our God and Father Himself--and our Lord Jesus--guide us on our way to you;

Thus He will build up your characters, so that you will be faultlessly holy in the presence of our God and Father at the Coming of our Lord Jesus with all His holy ones.
