Acts 16:5

So the churches were strengthened in the faith, and increased in number daily.

Having been freed, for the time being, from the troublesome insistence of the Judaizers, the churches prospered spiritually and numerically. The issue, however, was not dead; the Pharisee-Christians would trouble the whole world of that day by their efforts to subvert Christianity by mixing elements of Judaism with it; and the issue would not be effectively removed until the armies of Vespasian and Titus removed the Jewish state, the daily sacrifices, and the temple itself in 70 A.D., a full twenty years later. The books of Hebrews and Romans were addressed, in part, to this very issue; and Galatians, written about this time (50 A.D.), is full of it.

How strange it is that the Judaizers have never disappeared. Even now, nearly two millenniums afterward, the Judaizers are still in business: (1) attempting to bind sabbath-observance on Christians, (2) dragging instruments of music into the worship (even though David himself was condemned for that), (3) devising daily "sacrifices," such as that of the Mass, (4) ordaining a "priesthood" separate from the "laity," (5) the lighting of sacred candles, (6) the requirement of certain periods of official, formal fasts, and (7) the imposition of diet restrictions, etc., etc.
