<p>3:30&nbsp;<i>Since God is one</i>- The belief which the Jews held most dear; they felt that their monotheism divided them from the rest of the world. But it is the fact that there&rsquo;s only one God which binds together Jew and Gentile believers in Christ; for that one God justifies each human being on the same basis. The seriousness of our personal positions and the wonder of His saving grace is such that any ethnic difference between us becomes irrelevant.&nbsp;</p><p>That God is one is not just a numerical description. If there is only one God, He therefore demands our&nbsp;<i>all</i>. Because He is the One God, He demands all our worship; and because He is One, He therefore treats all His people the same, regardless, e.g., of their nationality (Rom. 3:30). All true worshippers of the one God, whether Jew or Gentile, are united in that the one God offers salvation to them on the same basis. The fact there is only one Lord Jesus implies the same for Him (Rom. 10:12). Paul saw these implications in the doctrine of the unity of God. But that doctrine needs reflecting on before we come to grasp these conclusions.<br />Paul, writing to those who thought they believed in the unity of God, had to remind them that this simple fact implies the need for unity amongst us His children, seeing He treats us all equally as a truly good Father: &quot; If so be that God is one... he shall justify the circumcision by faith, and likewise the uncircumcision through faith&quot; (Rom. 3:30 RV). Unity amongst us is inspired by the fact that God seeks to be one with us, exactly because He is Himself 'unity', one in Himself. The Rabbis have always been at pains to point out the somewhat unusual grammar in the record of creation in Genesis 1, which literally translated reads: &quot;One day... a second day... a third day&quot;, rather than 'One day... two days... three days', as we'd expect if 'Day one' solely referred to 'firstness' in terms of time. &quot;The first day&quot; (Gen. 1:5) therefore means more strictly 'the day of unity', in that it refers to how the one God sought unity with earth. &quot;<i>Yom ehad,&nbsp;</i>one day, really means the day which God desired to be&nbsp;<i>one</i>&nbsp;with man... the unity of God is a concern for the unity of the world&quot;.</p><p><i>He will justify the circumcised by faith and the uncircumcised by faith</i>- The Greek words&nbsp;<i>ek</i>&nbsp;&ldquo;by&rdquo; and&nbsp;<i>dia</i>&nbsp;faith AV &ldquo;through&rdquo; may simply be being used in parallel, meaning effectively the same thing, as they are in Gal. 2:16. &ldquo;The circumcision&rdquo; refers to Jewish Christians who believed; &ldquo;the uncircumcision&rdquo; is perhaps also a technical term, in this context, for believing Christian Gentiles.</p>
