In our own human nature, forgiving may be a difficult thing to do. The first instinct that comes to us is to retaliate when we are being offended. But as christians we need to do away which such kind of mindset. The topic states "Learning how to forgive," which means that forgiveness is learnt. Some people may be naturally tolerable, but only to an extent.
But what God wants is for us to have no boundaries to forgiveness. It's okay to feel hurt. We are humans. Choosing to let go does not mean we don't have feelings. It means that we are not allowing ourselves to be led by our emotions. It's okay to express our feelings and not bottle it up. But we shouldn't let them control us.
Emotions can be dangerous if we let it get the better of of us. The bible doesn't encourage unforgiveness. When we have the spirit of God in us we understand that it cannot stay in the same place where strive and unforgiveness resides. All those things are burdens and all they do is weigh down the spirit.
We should have a heart of forgiveness. That the kind of heart that is expected of us by God.
As christians, we should always forgive those who offend us so that our father in heaven will forgive us our sins.
