<p>6:13&nbsp;<i>Neither present your members to sin as instruments of unrighteousness-</i> &ldquo;<em>Instruments&rdquo; is</em> s.w. armour, weapon (Jn. 18:3; 2 Cor. 6:7; 10:4). We are called to fight, to serve in the army- of either sin or Christ. No passivity or wavering between the positions is therefore possible. We have changed sides. See on 6:23.</p><p><i>But present yourselves to God, as alive from the dead; and your members as instruments of righteousness to God</i>- The aorist tense could suggest a one time presenting of ourselves- at baptism? And if we didn&rsquo;t appreciate at the time of our baptism that this is what we were doing, we can do it now. Maybe that explains the otherwise difficult to translate tense usage here.</p>
