29 And where does that leave our proud Jewish claim of having a corner on God? Also canceled. God is the God of outsider non-Jews as well as insider Jews. 30 How could it be otherwise since there is only one God? God sets right all who welcome his action and enter into it, both those who follow our religious system and those who have never heard of our religion.
Matthew Henry's Commentary on Romans 3:29-30
Commentary on Romans 3:27-31
(Read Romans 3:27-31)
God will have the great work of the justification and salvation of sinners carried on from first to last, so as to shut out boasting. Now, if we were saved by our own works, boasting would not be excluded. But the way of justification by faith for ever shuts out boasting. Yet believers are not left to be lawless; faith is a law, it is a working grace, wherever it is in truth. By faith, not in this matter an act of obedience, or a good work, but forming the relation between Christ and the sinner, which renders it proper that the believer should be pardoned and justified for the sake of the Saviour, and that the unbeliever who is not thus united or related to him, should remain under condemnation. The law is still of use to convince us of what is past, and to direct us for the future. Though we cannot be saved by it as a covenant, yet we own and submit to it, as a rule in the hand of the Mediator.
