"Reckon yourselves to be dead indeed to sin, but alive to God." The force of the saying lies in "reckon yourselves." Settle it in your mind and heart. Compose yourselves in your inward resolves, knowing that you are already dead to sin and alive only for God.
Therefore allow no movement toward the first, and direct all your zeal toward the second. If someone became convinced that he was bodily dead, whatever happened around him would not concern him. Whatever those around him invited him to do, he would have one answer to everything: I am already dead; nothing concerns me.
So, he says, be this way toward sin. Have not only no movement toward it, but not even attention to it. It does not exist for you, and you do not exist for it.
On the other hand, as some wound machine, such as a clock, does nothing but show the time, so you should do only this. Have only this concern: how to live according to God and please Him.
Only, what the machine does involuntarily, you must do voluntarily. Do it with such willing self-compulsion, or with the consciousness of such moral necessity to act thus and not otherwise, as exists in a machine without its will.
"In Christ Jesus our Lord" means either "for the sake of Christ Jesus," because such are the conditions of salvation in Him. Our salvation is so ordered by Him and in Him that it cannot be otherwise.
Being united with Him by faith and grace through the holy mysteries, we cannot be in Him as we must be except by showing ourselves dead to sin and alive only for God. Whoever is not such does not belong to Christ.
Or "in Christ Jesus" means by the power of Christ Jesus. Be of good hope that you will truly remain such, for Christ the Lord is with you. He will accomplish this in you, if you remain devoted to Him.
On the other hand, however lofty it is to be dead to sin and alive to God, do not exalt yourself or think highly of yourself. It is not you who have accomplished and are accomplishing this, but Christ the Lord, with Whom you have been united.
Yet even to union with Him you were called by His goodness. You were brought into this union by His grace, and you remain in it by His help and overshadowing. This happens only because you willingly surrender yourself to His all-accomplishing activity within you.
