A. Load Your Conscience with the guilt of sin.
1. Dwell on the guilt which comes from the law. Every one of your sins merits hell. If there is unfortified sin in your heart you have no assurance you are free from the condemnation of sin. If the law does not convict you, woe on you! (Ps. 51:3; Gal. 3:24)
2. Bring your lust to the gospel. Look on him whom you have pierced (Zech. 12:10; Jn. 19:37). Do this daily.
3. Be Specific. Meditate upon the infinite patience and forbearance of God towards you and this sin. Load your mind with God’s gracious dealings toward you. Realize you deserve to be turned over to your sin and to be hardened. Don’t give your conscience any reason to excuse your sin
B. Passionately desire deliverance from the power of sin.
2 Cor. 7:11; Rom. 7:24; Ps. 38, 42. Be in constant prayer about deliverance (Luke 21:36).
C. Be aware your sin may be a fueled by your personality or upbringing.
This does not excuse your sin (Ps. 51:5). If you are not vigilant Satan will gain a foothold. The only way to conquer such a sin is through bodily discipline (1 Cor. 9:27). Bodily discipline in itself is not enough.
D. Discover the ways your sin seeks to gain a foothold and be on guard against them.
Watch [and pray] against any eruption of your corruptions (Luke 21:34).
E. Resist vehemently the first thoughts or acts of your sin.
Do not walk even a yard with your sin. James 1:14-15, stop it as it tries to start. Resist it with more vigor then it assails you.
