“If I had cherished sin in my heart, the Lord would not have listened; but God has surely listened and has heard my prayer. Praise be to God, who has not rejected my prayer or withheld his love from me!” Psalm 66:18-20
Asking for forgiveness is one of the hardest things to do, mostly because it requires admission of guilt. If you have wronged a friend—and whether or not your friend knows you have wronged them—you naturally avoid eye contact or avoid their presence altogether. You certainly would not be calling on them to do you any favors.
If you knew approaching your friend with an apology would mean reconciliation, you might be more likely to attempt the hard conversation, but most of the time your chances are fifty-fifty at best.
With God you never need to fear rejection if you approach him with a repentant heart. He’s your loving heavenly Father who wants nothing more than to be in a relationship with you, to hear your requests, and to grant the desires of your heart. The chances of reconciliation with God are one hundred percent. He already knows what you have done. He even knows your motives, and he loves you anyway. So you might as well come clean.
