Offense is an obstacle to love. And the cost of unresolved offense is great. For this cause, God takes it very seriously. No matter your personality, the prescription for resolution is universal. God is the resource and reason for loving others. Matthew 5:21-47
The Necessity of Resolving Offense | Vertical Living: 
There are no enduring relationships without forgiveness.
If you think you have the right to withhold forgiveness it is because you have not properly calculated the debt of sin owed to a Holy God. Even when it’s hard… Even when it’s hurtful… Forgiven people forgive people. You might be surprised what Jesus said hangs in the balance when it comes to forgiveness.
Forgive without limit…THIS is what we do.
