Romans 10
The tragedy of Romans 10 is Israel's zeal without knowledge—they are zealous for God but not according to knowledge, for failing to understand the righteousness of God, they seek to establish their own righteousness and have not submitted to the righteousness of God. Christ is the telos (goal, end, fulfillment) of the law for righteousness (dikaiosynē) to all who believe; the law's aim is fulfilled not through its observance but through faith in the One it foreshadows. Paul's famous confession formula—if you confess with your mouth Jesus as Lord (Kyrios) and believe in your heart that God raised him from the dead, you will be saved—structures righteousness (by faith) and salvation as inseparable, for with the heart one believes unto righteousness and with the mouth confesses unto salvation. The chain of faith extends through hearing, hearing through the word of Christ, and the beautiful feet of those who bring the good news (Isa 52:7) who proclaim the gospel of peace and good things; yet Israel has heard—their voice has gone out to all the earth (Psalm 19)—but did not believe, for faith comes by hearing and hearing by the word of God. The hardening is not absolute but strategic: God gave them a spirit of stupor, eyes not to see and ears not to hear, drawing from Isaiah 29, suggesting that Israel's unbelief is neither arbitrary nor final but part of God's purposes in bringing the gospel to the Gentiles and, implicitly, in creating space for Gentile inclusion.
