For you were bought at a price; therefore, glorify God in your body and in your spirit, which are God’s. – 1 Corinthians 6:20

Obedience arises out of a faith which is to us the paramount principle of action. The kind of faith which produces obedience is lord of the understanding, a royal faith. The true believer believes in God beyond all his belief in anything else, and everything else. He can say, “Let God be true, but every man a liar.” His faith in God has become to him the crown of all his believings; the most assured of all his confidences. As gold is to the inferior metals, such is our trust in God to all our other trusts. To the genuine believer the eternal is as much above the temporal as the heavens are above the earth. The infinite rolls, like Noah’s flood, over the tops of the hills of the present and the finite. To the believer, let a truth be tinctured with the glory of God, and he values it; but if God and eternity be not there, he will leave these trifles to those who choose them. You must have a paramount faith in God, or else the will of God will not be a paramount rule to you. Only a reigning faith will make us subject to its power, so as to be in all things obedient to the Lord. The chief thought in life with the true believer is, “How can I obey God?” His great anxiety is to do the will of God, or acceptably to suffer that will; and if he can obey, he will make no terms with God, and stand upon no reservations. He will pray, “Refine me from the dross of rebellion, and let the furnace be as fierce as Thou wilt.” His choice is neither wealth, nor ease, nor honour; but that he may glorify God in his body, and his spirit, which are the Lord’s. Obedience has become as much his rule as self-will is the rule of others. His cry unto the Lord is, “By Thy command I stay or go. Thy will is my will; Thy pleasure is my pleasure; Thy law is my love.” ~ C.H. Spurgeon
