'Desire' in the Bible

But if, while we seek to be justified in Christ [by faith], we ourselves are found to be sinners, does that make Christ an advocate or promoter of our sin? Certainly not!

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.
