<p>10:16 <i>But they did not all obey the glad tidings. For Isaiah said: Lord, who has believed our report?- </i>This is one of a number of instances of where Old Testament Messianic Scriptures are applied to Paul in the context of his preaching Christ. What is true of the Lord Jesus must be true of us, if we are &quot;in Him&quot; and counted by God as Him. In Judaism, the prophets were seen as a saintly group to whom no ordinary person could pretend. But both the Messiah and Isaiah are here being cited as patterns for all who are &quot;in Christ&quot;. The identity between Christian preachers and Isaiah also demonstrates that the essence of the Gospel &quot;glad tidings&quot; was preached in the Old Testament. Isaiah's lament here is of Judah refusing the good news of Messiah in his day, and that is just what happened in the first century. Isaiah's lament is that despite the amazing achievement of Messiah and God's offer of grace in Him, Jewry generally had not believed it.</p><p>The theme of Romans is the Gospel, and in this context Paul makes the point that because both Jew and Gentile are saved by the Gospel, <i>therefore</i> we should preach to both Jew and Gentile (Rom. 10:9-18). In this context, Paul quotes from Is. 52:7 and Nah. 1:15, both concerning preaching to Israel: &quot;How shall they hear without a preacher? as it is written, How beautiful are the feet of <i>them</i> (cp. 'he' in the originals- our preaching is a manifestation of the Lord) that preach the Gospel of peace, and bring glad tidings&quot;. The Nahum passage is in the context of preaching to Israel the good news of their ultimate freedom from the Assyrian invasion which was then imminent. We are in a strikingly parallel situation in these last days. Rom. 10:16 then goes on to quote Is. 53:1, which again refers to the preaching of the Gospel to Israel, and applies it to our preaching.</p>
