<p>1:5 <i>And this is the message which we have heard from him and announce to you: That God is light, and in Him is no darkness at all</i>- There is a negative attached to all truths; if something is true, then therefore other things or ways of life are not true. There are several Bible passages which bring out this dualism.</p><div align=center><table border=0 cellspacing=10 cellpadding=0 width=80%>    <tbody>        <tr>            <td width=369 valign=top>            <p>            &quot;God is light</p>            </td>            <td width=369 valign=top>            <p>and in   Him there is no darkness&quot; (1 Jn. 1:5)</p>            </td>        </tr>        <tr>            <td width=369 valign=top>            <p>&quot;God   is faithful</p>            </td>            <td width=369 valign=top>            <p>and   there is no unrighteousness in him&quot; (Dt. 32:4)</p>            </td>        </tr>        <tr>            <td width=369 valign=top>            <p>&quot;God   is righteous</p>            </td>            <td width=369 valign=top>            <p>and   there is no unrighteousness in him&quot; (Ps. 92:16)</p>            </td>        </tr>    </tbody></table></div><p>It is therefore quite valid to understand that a set of true teachings by their very nature give rise to a set of untrue ones, to be rejected. But more personally relevant for each one of us, each truth we perceive leads to not only things we should do, but things we should not.</p><p>The references to light and darkness further allude to the prologue of John's Gospel. The word &quot;was God&quot;, and was the light which shone in the darkness of the Jewish world, to which the Jewish world would not come because they preferred the darkness. John's converts were Jews, and the temptation to return to Judaism, or compromise with it, was strong. He therefore presents the light of Christ as being effectively the light of God, and compromise with the darkness was by nature impossible.</p>
