28 Therefore we conclude that a man is justified by faith apart from the deeds of the law. 29 Or is He the God of the Jews only? Is He not also the God of the Gentiles? Yes, of the Gentiles also, 30 since there is one God who will justify the circumcised by faith and the uncircumcised through faith.” (Romans 3:28–30, NKJV)
God’s promise to Abraham was that “in your seed all the nations of the earth shall be blessed” (Gen. 22:18). The seed of which He spoke was Christ (Gal. 3:16). In this age of inclusiveness it is vital to see the inclusive nature of the gospel is not about everyone deciding truth for themselves (whether that “truth” is Hinduism, Buddhism, Islamic, Judaic, Catholic, Protestant, Orthodox, atheistic, agnostic, ad nauseam). God includes all of humanity in one blessed way of justifying sinners. The way of salvation is Christ and is revealed in His gospel. Israel was not justified by the law of Moses (Rom. 2). Gentiles were guilty and under wrath through their unbelief, idolatry and immorality (Rom. 1:18-32). There is one God over all humanity. God justifies Jews “by faith.” The gospel (the law of faith, Rom. 3:27), not the law of Moses, is how Jews are saved. God justifies Gentiles “through” faith. The gospel (the law of faith, Rom. 3:27), is how Gentiles are saved. We do not keep the law of Moses or add anything else to the gospel in order to be saved (see this applied in Gal. 5:3-6). God justifies sinners by “faith” – one faith, not many (Eph. 4:5). The gospel of Christ is sufficient to save sinners (Rom. 1:16). To include other “faiths” nullifies its power and forfeits grace (Gal. 1:6-9).
