Commentaries:
A changed heart comes only from the presence of God's Spirit, and there was no provision in the Old Covenant for receiving God's Spirit. Because it is a process, there is a sequence to salvation. God calls and leads to repentance. The person begins to have faith in God and to become aware of sin, so he repents of sin. Now he is in a position to receive the Holy Spirit. He becomes baptized and has hands laid on him to receive the Holy Spirit. He has begun the process that will lead to salvation. None of these provisions were part of the Old Covenant.
