Paul describes the discipline of integrity by comparing it to the effective but temporal—“bodily exercise” (I Timothy: 7–8). Paul is agreeing that we need to care for our bodies, and exercise is a part of that care. As God’s Temple, we care for our bodies, so they can be used for His glory
(1 Cor. 6:19–20). We also want our bodies fit when we present them as instruments God can use in His service (Rom. 12:1–2).
