Our society doesn’t glorify discipline all that much. This means it may take you some time to learn a disciplined lifestyle.
The apostle Paul said we’re to be like Olympic athletes, beating our bodies and running so as to win. Most of us haven’t disciplined our bodies to that extent, certainly not in the sexual arena. But the truth is clear. We’re to crucify the flesh. Part of that process is learning not to put yourself in the same old situations that lead to sin.
Whatever your defense, set your rules and then be disciplined.
Let us throw off everything that hinders and the sin that so easily entangles, and let us run with perseverance the race marked out for us. Let us fix our eyes on Jesus, the author and perfecter of our faith, who for the joy set before him endured the cross, scorning its shame, and sat down at the right hand of the throne of God. Consider him who endured such opposition from sinful men, so that you will not grow weary and lose heart. (HEBREWS 12:1-3)
