Liberation and salvation. By his glorious Cross Christ has won salvation for all men. He redeemed them from the sin that held them in bondage. "For freedom Christ has set us free." In him we have communion with the "truth that makes us free." The Holy Spirit has been given to us and, as the Apostle teaches, "Where the Spirit of the Lord is, there is freedom." Already we glory in the "liberty of the children of God."
