“For it pleased the Father that in Him all the fullness should dwell, and by Him to reconcile all things to Himself, by Him, whether things on earth or things in heaven, having made peace through the blood of His cross.” (Colossians 1:19–20, NKJV)

Jesus Christ is the fullness of God. It pleased the Father that all fullness should abide in him. And then there is the need for reconciliation. One of Jesus Christ’s missions is to reconcile all things to God. This includes both the things that are on earth and the things that are in heaven. And he accomplished this reconciliation through the blood that he shed on the cross. Why is there need for reconciliation? Because when sin entered the universe and ultimately the world and mankind, a great chasm was opened that separated us from God. Jesus Christ bridges that chasm and reconciles all things to God. God takes back from Satan that which he had stolen from God in the first place. And now there is peace through the blood of his cross.
