Rom. 8:13 - Promise of Life Not Made to the Work of Mortification But to Him Who Works, For Christ's Sake

Robert Haldane on Romans 8:13:

• For if you live after the flesh, you shall die: but if you through the Spirit do mortify the deeds of the body, you shall live. 
• "Ye shall live." — Here eternal life is promised to all who, through the Spirit, mortify the deeds of the body. The promise of life by the Gospel is not made to the work, but to the worker; and to the worker, not for or on account of his work, but according to his work, for the sake of Christ’s work. The promise, then, of life is not made to the work of mortification, but to him that mortifies his flesh; and that not for his mortification, but because he is in Christ, of which this mortification is the effect and the evidence. That they who mortify the flesh shall live, is quite consistent with the truth that the gift of God is eternal life, Romans 6:23; and in this gift there is no respect to the merit of the receiver. This describes the character of all who shall receive eternal life; and it is of great importance. It takes away every ground of hope from those who profess to know God, and in works deny Him; for they that are Christ’s have crucified the flesh with the affections and lusts.  [Robert Haldane, Commentary on Romans]
