That's part of your communion with God. Bring it up and may it become as detestable to me as it is to you, and may you give me the strength to see it go away. Those are the kind of prayers that are the true prayers of repentance. That's my heart's cry. And then prayer exposes secret sins.
Prayer weakens prevailing sins.
Prayer finds strength in fellowship with the Holy God to kill sin in our lives. First, I have to recognize the sin in my life. Don't kid yourself, don't gloss over yourself, don't underestimate your wretched condition as Paul didn't in Romans, chapter 7. And then fix your gaze wholly on God and become totally devoted to Him, so that everything in life, center and circumference, is Him. And then it is also equally essential that you cultivate a knowledge and understanding, and a deep comprehension and application of Biblical truth, and that you spend time in honest prayer before God, bringing the truth to life in His presence.
