Romans 10:18-11:1 But I ask, have they not heard? Indeed they have, for "Their voice has gone out to all the earth, and their words to the ends of the world." 19 But I ask, did Israel not understand? First Moses says, "I will make you jealous of those who are not a nation; with a foolish nation I will make you angry." 20 Then Isaiah is so bold as to say, "I have been found by those who did not seek me; I have shown myself to those who did not ask for me." 21 But of Israel he says, "All day long I have held out my hands to a disobedient and contrary people." 11:1 I ask, then, has God rejected his people? By no means! For I myself am an Israelite, a descendant of Abraham, a member of the tribe of Benjamin.
Please notice a very important thing the Apostle Paul is doing to bring unity in the local church in Rome. He keeps bringing the people back to the word of God. He is making the point that even though the nation Israel has not received God’s righteousness by faith, God has not rejected the Israelites. He uses four different Scripture references (see below) to show that God is using the Gentiles to make the Israelites jealous to receive Jesus Christ as their Savior. He states the fact that he is an Israelite who has been saved by faith in Jesus Christ, even though the nation of Israel remains disobedient and continues to pursue the righteousness of the law by works and not by faith. Paul shows from scripture that God is saving both Jew and Gentile by faith. The Gentile or Jew, who is saying differently and causing division, is shown to be going against the scriptures.
How do we bring unity between people of faith? We bring both sides back to the scriptures. This truth works in families, businesses, local churches and wherever Christians work together to accomplish God’s assignment. When we have all the Christians working together in unity, we have a greater harvest. When we have Christians divided while working their God-given assignment we will have less of a harvest. The key for a united group effort is to bring opposing sides in line with the word of God.
