The Hebrew writers, speaking of the great blessings that come by faith in Christ said that we who live by faith in Him have come to, “to the general assembly and church of the first-born who are enrolled in heaven, and to God, the Judge of all, and to the spirits of righteous men made perfect.” (Heb. 12:23)
It is by faith and in His church that we are perfected. This is part of the great blessing that comes by faith — perfection, inclusion into His church, and fellowship with God.
This fullness of blessings is something that the law could never do. As Paul told the Galatians:
Gal. 3:2,3“…did you receive the Spirit by the works of the Law, or by hearing with faith? Are you so foolish? Having begun by the Spirit, are you now being perfected by the flesh?”
Paul told that that the Spirit made perfect, and the Spirit did not come come by the Law. (Remember those disciples that Paul met in Ephesus who had lived under the law and by John’s teaching who hadn’t even heard of the Spirit yet.)
So the great blessings that we seek are by the life of faith. As Habakuk prophesied so long ago that great message of the gospel:
Hab. 2:4 “Behold, as for the proud one, His soul is not right within him; But the righteous will live by his faith.”
Live by faith, justified by faith, perfected by faith. Faith in Christ counts for all. Have and grow that faith.
