2 Peter 3:9-17
Philippians 4:6-7, “Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God. And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.”
The Bible commands us to be careful (anxious) for nothing, yet one of the most common problems among Christians is the matter of guilt, which leads to discouragement. Many feel beaten down by it as they dwell on their inadequacies and failures. They fret about their weaknesses, and somehow are of the belief that if they could undo the past, things would be different; on the other hand, they know they cannot. They see others as carefree, while they themselves are burdened down with feelings of wrongdoing.
As a result, such people are spiritually crippled. They are falling far short of their potential as servants. They brood, dwelling in dark valleys of self-condemnation simply because they have never learned to face and resolve the problem of guilt. Because this affects so many Christians we need to learn to overcome it.
If we deal with it in a courageous manner, I believe it will help us to live the Christian life at its best.
