We are not debtors to the flesh (Romans 8:12), only by necessity of nature, so far as not to starve them. But for corrupt nature, which inclines to please the flesh more than God, and to care for it above the soul, to this we are not debtors. We are debtors to the Spirit. It is the Spirit’s work to convince of sin, to witness against it, to restrain from it, and to mortify it: our new nature inclines towards it; our privileges oblige us to it; we are debtors for this, and debtors for it to the Spirit. And this debt we own in baptism, wherein we renounce the false trinity, and dedicate ourselves to the true (Romans 6:11). Baptism’s a vowed death to sin; therefore the apostle argues against living to sin (Romans 6:3-4; Romans 6:2; Colossians 3:3, 5). The apostle Peter tells us it’s not the external part of it, or the putting away of the filth of the flesh, that effects this, but the answer of a good conscience towards God (1Peter 3:21). God puts this question to your conscience, do you renounce sin and Satan? The good conscience says yes and does it. Now, he only is a true Christian, who makes conscience of paying this debt: If sin gets any power over him, it is not of right, he owes nothing to it. And this may be his answer to the flesh when it tempts, I owe you nothing!
