'Conflict' in the Bible

So is the Law in conflict with the promises of God? Of course not! For if a law had been given that could give us life, then certainly righteousness would come through the Law.

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.
