Psalm 118:12

Our Lord Jesus, by His death, did not purchase a right to only a part of us, but to the entire person. He contemplated in His passion the sanctification of us wholly—spirit, soul, and body—that in this triple kingdom He Himself might reign supreme without a rival. It is the business of the newborn nature, which God has given to the regenerate, to assert the rights of the Lord Jesus Christ.

My soul, so far as you are a child of God, you must conquer all the rest of yourself which yet remains unblessed. You must subdue all your powers and passions to the silver scepter of Jesus’ gracious reign, and you must never be satisfied until He who is King by purchase also becomes King by gracious coronation, and reigns in you supreme.

Since, then, sin has no right to any part of us, we engage in a good and lawful warfare when we seek, in the name of God, to drive it out. O my body, you are a member of Christ: shall I tolerate your subjection to the prince of darkness?

O my soul, Christ has suffered for your sins and redeemed you with His most precious blood: shall I allow your memory to become a storehouse of evil, or your passions to be firebrands of iniquity? Shall I surrender my judgment to be perverted by error, or my will to be led in fetters of iniquity? No, my soul, you are Christ's, and sin has no right to you.

Be courageous concerning this, O Christian! Do not be dispirited, as though your spiritual enemies could never be destroyed. You are able to overcome them—not in your own strength, for in that strength even the weakest of them would be too much for you—but you can and shall overcome them through the blood of the Lamb. Do not ask, “How can I dispossess them, for they are greater and mightier than I am?” but go to the Strong One for strength, wait humbly upon God, and the mighty God of Jacob will surely come to your rescue, and you shall sing of victory through His grace.
