J. Gresham Machen mentions why all thanks & praise is due to our Savior & Lord, while writing on the active obedience of Christ in our salvation…
Christ took our place with respect to the law of God. He paid for us the law’s penalty, and He obeyed for us the law’s commands. He saved us from hell, and He earned for us our entrance into heaven. All that we have, then, we owe unto Him. There is no blessing that we have in this world or the next for which we should not give Christ thanks.
— The Active Obedience of Christ, p. 191, in Machen’s GOD TRANSCENDENT (1949; Banner of Truth edition, 1982).
