Bought back

1 Cor. 6:20 “For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s.”
1 Cor. 7:23 “Ye are bought with a price; be not ye the servants of men.
1 Cor. 6:19 “What? know ye not that your body is the temple of the Holy Ghost [which is] in you,which ye have of God, and ye are not your own.”

When we are redeemed or bought back the bible says we are not our (referring to old self) own. This tells me we are His. If we are His then we are our own in Him which is different. We were set free from ourselves by Him nailing to the cross that which was against us and contrary to us. We are under His authority and Lordship and serve in a new way of the Spirit because we want to. We want to because our will and whole creature was purchased at Calvary. Our will is His will and His will is ours. There is probably a tupos of redemption somewhere in the O.T., not sure where.
