LET THE FLESH OF THE SAINTS BE GLAD.
For if the earth has to suffer either joy or injury, it is simply on people’s account, that they may suffer the joy or the sorrow through the events that happen to their dwelling place, whereby they will rather have to pay the penalty that, simply on their account, even the earth must suffer. When, therefore, God even threatens the earth, I would prefer saying that he threatens the flesh. So likewise, when he makes a promise to the earth, I would rather understand him as promising the flesh; as in that passage of David: The Lord is King, let the earth be glad, meaning the flesh of the saints, to which appertains the enjoyment of the kingdom of God.
