3:25

now that the faith has arrived: Jesus is the only person who fulfilled the Law perfectly. So Paul could say that the faith​—that is, perfect faith​—had arrived. By fulfilling the Law, Jesus gave his followers the opportunity to have an approved standing with Jehovah God. He thus became the “Perfecter of our faith.” (Heb 12:2) Christ would be with his disciples “all the days until the conclusion of the system of things” (Mt 28:20), so there is no need to go back to the care of the guardian. (See study note on Ga 3:24.) Using this reasoning, Paul makes the point that the Mosaic Law became obsolete with the arrival of this perfected faith based on Jesus Christ.
