Real forgiveness includes a cancellation of the penalty for the wrongdoing. The reason being that Jesus paid the complete penalty for us through His death on the cross.
 
Many people, when they sin, expect something bad to happen to them. Then, when it does, they blame the bad thing on God as though God is punishing them. But take Jesus' words personally, "Son, Daughter, your sins are forgiven and the penalty remitted." What great news!
 
Now let's add a new dimension to this. Since we are children of God, God teaches us to forgive people, just like he forgives us! When someone hurts you or wrongs you, can you, from the heart, forgive them and remit the penalty? In other words, can you forgive them and treat them just as if they had never wronged you? This means you won't try and punish them in any way, like not talking to them, treating them rudely, excluding them from things, or having an attitude around them, etc. When God asks us to act like Him, He gives us the grace-divine, beyond human ability, to do so. That is the only way to live the Christian life! When you try and obey God or live the Christian life by your own power, you are going to fail. God has to give you His ability. This is done by an impartation of the grace of God.
