34 “Command, O God, Your Virtue”. For one is our Lord Jesus Christ, through whom are all things, and we in Him, of whom we read that He is “the Virtue of God and the Wisdom of God.” But how does God command His Christ, save while He commends Him? For “God commends His love in us, in that while yet we were sinners, for us Christ died.” “How has He not also with Him given to us all things?” “Command, O God, Your Virtue: confirm, O God, that which You have wrought in us.” Command by teaching, confirm by aiding.
