Ideas about the Kingdom of the Heavens around us and the unity of believers in Christ within it
When Jesus said that the son of man has power to forgive sins on Earth, he was referring to his humanity–and ours. God has already forgiven. Like Jesus, we have the power–and the mission–to offer forgiveness on Earth.
My forgiveness or unforgiveness of you has real power. If I hold onto a grudge against you, or you hold onto a grudge against me, it binds both of us, limits the Body of Christ, and affects the whole world, until it is released. So we must properly deal with grudges.
Our disunity also leads to the multiplication of wrongs and injustices between us, often motivated by our greed. These wrongs lead to lawsuits among us. To our shame, we look just like the world in this matter!
