<p>5:16 <i>But I say, walk by the Spirit and you shall not fulfil the lust of the flesh</i>- Having quit trusting in grace for salvation, the Galatians found that their flesh lusted against the spirit to the extent that they just couldn&rsquo;t do the things they knew they should and which obedience they now so desperately desired- because they were not led of the spirit, they were still under law (Gal. 5:18). They didn&rsquo;t have a spiritual way of life, instead they were just trying to keep certain specific commandments, and they found they just couldn&rsquo;t live a victorious spiritual life.&nbsp;</p><p>How to not sin is perhaps one of our most fundamental questions. The answer the legalists gave was: 'By obedience'. But that throws the question only a stage further back. How? Paul has said that if we really believe we will be saved, then we will be; and the promised inheritance is by grace and not obedience to a set of laws. Those who believe this will give their whole lives in joy and response to that great salvation; they have no set of laws to follow, but the Spirit of Christ will be put into their hearts which leads them to &quot;love&quot;, which outworks in lives of service to others. Thus they will lead lives 'walking by the Spirit', living life in that sphere of being and thinking; this is the way to not fulfil the lusts of the flesh. Those who try to battle each temptation in their own strength will find themselves torn by the conflicting desires and passions which destroy so many religious people and make them nothing less than neurotic. Joy and peace as promised by the Lord will just not be realized by them.&nbsp; The Galatians are really a parade example; they switched over to trying to defeat each lust and passion as it arose, without the help of the Spirit and without the assurance of being secured in Christ by grace. And they started to fail, miserably. The misery of their position is well described in :17.</p>
