Bible Study Romans 10
Israel’s Unbelief
Their zeal is not in line with the truth means that the Jews’ passion for God was strong, but it ignored the true righteousness of God (v. 3; cf. also 3:21).
Their lack of knowledge was self-inflicted. Refuse the truth and God will give you up to your own foolishness.44
The only thing God requires of people is that they not persist in trying to earn what they can only receive as a totally free gift. Their problem is that pride stands in the way of receiving God’s gift. Deeply ingrained in people’s hostility to divine grace is a proud and stubborn self-reliance that would rather suffer loss than be deprived of an occasion for boasting.
Those who come to Christ by faith are acknowledging that they have placed themselves entirely and without reserve under his authority to carry out without hesitation whatever he may choose for them to do. There is no such thing as salvation apart from lordship.
Outward confession stems from a profound inward conviction. Those who come to Christ must believe in their hearts that Jesus was raised from the dead by God the Father. The resurrection of Jesus Christ is the very center of the Christian faith. Apart from the resurrection Christianity would be little more than a well-intentioned ethical system.
All effective preaching is accomplished by God himself. The messenger is at best merely the instrument used by the Holy Spirit as a necessary part of the process. It is God’s own voice that confronts the sinner and offers reconciliation. This existential reality is what constitutes the gospel, “the power of God for … salvation” (Rom 1:16).
The answer implied in v. 19 is that if unenlightened people outside of the covenant could understand the gospel, then certainly a religiously gifted and highly favored group like the Jews had no grounds for claiming that it was beyond their understanding.
