We always give thanks to God for all of you, mentioning you in our prayers,

 Paul sends this letter to the church of the Thessalonians which is in God and the Lord Jesus Christ. God was the very atmosphere in which the Church lived and moved and had its being. Just as the air is in us and we are in the air and cannot live without it, so the true Church is in God and God is in the true Church and there is no true life for the Church without God. Further, the God in whom the Church lives is the God and Father of our Lord Jesus Christ; and, therefore, the Church does not shiver in the icy fear of a God who is a tyrant but basks in the sunshine of a God who is love.
