What To Do After You Have Failed Morally

Failing is not a nice feeling for anyone to experience, especially when u fail morally and when it is that you do sincerely love the Lord. You feel genuinely sad and disappointed in yourself. But what you do after that is really up to you. You can either choose to seek for forgiveness, forgive your own self and move on, depending on God to help you or you wallow in the pit of self pity and resign yourself to the fact that probably nothing good can come from you. The end result of the latter is that the problem takes hold of a person and leads one down a road of morale decadence.
I strongly believe that we can go right back to the point of loving ourselves and God like that failure never even happened. God says that when he forgives our sins, he remembers it no more, and we should do same. We ought not to let the guilt remain with us, neither should we allow the taste of the pleasure of what we fell right back into remain with us. With God nothing is impossible and also nothing is impossible for them that believe. David was a man mightily used and mightily loved by God. Yet, he made serious blunders and still yet, God called him a "man after my heart". The key was his ability to sincerely repent before God in humility whenever he fell short of God's glory and that is the kind of heart we ought to have as Christians.
No one is infallible, but a life of purity is guaranteed with God. The key is to practice a life of complete dependence on the Holy Spirit and a holy life is possible.
