16 But I say, walk habitually in the [Holy] Spirit [seek Him and be responsive to His guidance], and then you will certainly not carry out the desire of the *sinful nature [which responds impulsively without regard for God and His precepts]. 17 For the sinful nature has its desire which is opposed to the Spirit, and the [desire of the] Spirit opposes the *sinful nature; for these [two, the sinful nature and the Spirit] are in direct opposition to each other [continually in conflict], so that you [as believers] do not [always] do whatever [good things] you want to do.
