10:1-4 The Jews built on a false foundation, and refused to come to Christ for free salvation by faith, and numbers in every age do the same in various ways. The strictness of the law showed men their need of salvation by grace, through faith. And the ceremonies shadowed forth Christ as fulfilling the righteousness, and bearing the curse of the law. So that even under the law, all who were justified before God, obtained that blessing by faith, whereby they were made partakers of the perfect righteousness of the promised Redeemer. The law is not destroyed, nor the intention of the Lawgiver disappointed; but full satisfaction being made by the death of Christ for our breach of the law, the end is gained. That is, Christ has fulfilled the whole law, therefore whoever believeth in him, is counted just before God, as much as though he had fulfilled the whole law himself. Sinners never could go on in vain fancies of their own righteousness, if they knew the justice of God as a Governor, or his righteousness as a Saviour.
3. For they being ignorant of God's righteousness—that is, for the justification of the guilty (see on Ro 1:17).
and going about—"seeking"
to establish their own righteousness, have not submitted themselves to the righteousness of God—The apostle views the general rejection of Christ by the nation as one act.
