“Now may our God and Father Himself, and our Lord Jesus Christ, direct our way to you; and the Lord make you to increase and abound in love one toward another, and toward all men, even as we also do toward you, to the end he may establish your hearts blameless in holiness before our God and Father, at the coming of our Lord Jesus with all his saints.”
—1 Thessalonians 3:11-13 WEB
Observe, Whom he prays to, namely, God and Christ. Prayer is a part of religious worship, and all religious worship is due unto God only. Prayer is here made to God, even the Father and our Father; and also to Christ, even our Lord Jesus Christ. Therefore Jesus Christ our Lord is God, even as God our Father is God. Prayer is to be offered to God as our Father. So Christ taught his disciples to pray; and so the Spirit of adoption prompts them to pray, to cry, Abba Father. Prayer is not only to be offered in the name of Christ, but offered up to Christ himself, as our Lord and our Saviour.
