<p>5:13- see on Jn. 8:32.</p><p><i>For you, brothers, were called for freedom</i>- This goes back to the allegory of the two sons. We are children of the free woman. But whilst all men pay lip service to a love of freedom, very few really want it once presented with it. To believe we really are saved and shall be saved by grace when the Lord returns... and that great salvation is independent of our sins and obedience... this is the ultimate freedom, and we shall be granted that freedom in a more material sense when our natures are changed and we enter God's Kingdom at the Lord's return. The way the Galatians turned away from freedom is so instructive as to the real nature of human thought and essential preference.</p><p><i>Only do not use your freedom as an opportunity for the flesh</i>- No Greek word represents &quot;use&quot;; the idea is that the freedom to law which we are called to is not an opportunity for fleshly behaviour, but rather that freedom paradoxically ends up in service to others, because the work of the Spirit produces love as its summary fruit (5:22).</p><p><i>But through love serve one another</i>- The Spirit produces love (:22), and that love is itself a motivating and activating power. Hence the GNB: &quot;Let love make you serve one another&quot;.</p>
