God, the Knower of hearts, then bore witness that He deemed them worthy of His saving grace, granting them the Holy Spirit as He had granted Him to Christians from the circumcision.
Consequently, God Himself made no distinction between the circumcised and the uncircumcised. By faith He directly purified the hearts of the latter, without first purifying their bodies by circumcision.
After this the apostle applies the matter to the question that had been raised. Addressing the unreasonable zealots of the law of Moses, he says the following.
Why then do you now, after such clear divine indications and testimonies, and after the will of God concerning the Gentiles has been so clearly expressed, tempt God?
Why do you still question Him, and demand from Him new signs and wonders in order to know His will?
Why do you wish to place upon the necks of the disciples a yoke which neither our fathers nor we were able to bear?
It is not the legal yoke that saves us. Rather, we believe that through the grace of the Lord Jesus Christ we shall be saved, even as they are (cf. Rom. 3:9-26; Gal. 2:15-16; 3:10-14).
