1 Brethren, my heart’s desire and prayer to God for Israel is that they may be saved. 2 For I bear them witness that they have a zeal for God, but not according to knowledge. 3 For they being ignorant of God’s righteousness, and seeking to establish their own righteousness, have not submitted to the righteousness of God. (Romans 10:1–3, NKJV)
Religious zeal can be misinterpreted as divine approval. The Jews of Paul’s day were trusting in the works of the law of Moses to save them (Romans 2:17-24; 3:20, 27-28). Not a few Jewish Christians were being influenced to demand Gentiles keep the law of Moses to be saved (Acts 15:1, 5, 23-24). The epistle to the Romans explains the futility of the Jewish attempt to be saved by the law of Moses, and to force it on the Gentiles. Paul said trying to be saved by the law of Moses amounted to establishing their own righteousness instead of submitting to the righteousness of God which is by faith in Jesus Christ (Romans 10:3; 1:16-17; Galatians 2:16). Paul desired the salvation of the Jews, but their zeal without knowledge would not save them. Zeal does not establish God’s approval, faithfully doing the Father does (Matthew 7:21-23). Zeal is not a substitute for knowing God’s will. Zealous ignorance is removed only when a humble heart hears the word of God and obeys it in faith (Matthew 7:24-27; Acts 3:17-19). Learn God’s will and have the faith to obey it to be saved from your sins (Acts 4:12; 10:34-35).
