Col. 1:19-21a For God in all his fullness was pleased to live in Christ and by him God reconciled everything to himself. He made peace with everything in heaven and on earth by means of his blood on the cross. This includes you who were once so far away from God.
God in all His fullness lived in Christ when Christ lived on earth. Jesus was the fleshly embodiment of God. He limited himself to life on earth and would not display all of His godliness while here, but it does not change who He is. Jesus is God and God is Jesus. There is no difference whatsoever between the two.
It pleased God to live His life on earth for a season. God did not take on human life reluctantly or begrudgingly. It was something He chose to do and it brought Him pleasure to do it because He loves us and knew that it was the only way we could really get to know Him and have a relationship with Him.
While on earth, God made everything right. Sin had distorted, divided, and destroyed the life that God had intended man to enjoy on earth. Everything and everyone was a mess. There was no way for man to live in peace and with the blessings of God upon him. Jesus took care of the problem we had created by our disobedience. He restored the way to fellowship with God. He made it possible for us to have peace with God and enjoy the blessings of God.
Through His dying on the cross, all people now have access to God. No one is without hope. If we want to be restored to a right relationship with God, we can be. No one is beyond the reach of God's love. Jesus forgives the sins of all who come to Him in faith, trusting in Him alone for forgiveness.
Even though no one deserves God's forgiveness, for everyone is guilty of sin and deserves an eternity spent in hell, all are forgiven who come to the cross, confesses their sins, and trusts in Christ as their Savior and Lord.
