Paul had begun to lament Israel's unbelief despite their privileges, affirmed God's sovereign mercy and election, and highlighted that true heirs are the children of promise through faith, not works
Now with chapter 10, Paul continues to nail down those points:
He expresses his heartfelt desire and prayer for Israel's salvation, acknowledging their zeal for God but criticizing it as misguided
They are without real knowledge of His righteousness, for they are without knowledge of the Father (John 8:18-20)
They sought to establish their own righteousness and did not submit to God's (v. 3), ignoring Christ as the fulfillment of the law for believers (v. 4\)
He teaches that righteousness comes by faith in Christ, not by striving to keep the law, and this was not access given only to Gentiles, but to all
Those who still rely upon the law are like those who blaspheme in the manner found in Deuteronomy 30 (vv. 12-13), which Paul quotes in verses 6 and 7
They ask who will ascend into heaven or descend into the abyss on their behalf?
By doing so, they disregard what Christ has already done for them, in having descended into the abyss and ascending into heaven
Rather, the one with belief would not even say such a thing in his heart, knowing that Christ has already done this
For we should follow as the apostle here explains Deuteronomy 30:14 was telling all man he must do, which was to confess Jesus as Lord and believe in His resurrection (vv. 9-10), for all who call on Him are saved (vv. 11-13).
He emphasizes the necessity of preaching the gospel for faith to arise, as the means by which Christ obtains His people
Faith comes upon the elect hearing the message of Christ (v. 17\)
Despite widespread proclamation (v. 18), Israel did not obey and Isaiah's prophecies were fulfilled in this
By Israel's disobedience/deafness
By the gentile's inclusion to the people of God
This chapter urges us to proclaim the accessible gospel boldly, trusting in God's sovereign plan to save all who believe, while acting as fuel for our prayers for the lost and gratitude for faith as His gift
