Galatians 5:16-17, 25

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]. 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.

If we [claim to] live by the [Holy] Spirit, we must also walk by the Spirit [with personal integrity, godly character, and moral courage—our conduct empowered by the Holy Spirit].
