'Conflict' in the Bible

Or what king, when he sets out to meet another king in battle, will not first sit down and consider whether he is strong enough with ten thousand men to encounter the one who is coming against him with twenty thousand?

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.

[and so you are] experiencing the same [kind of] conflict which you saw me endure, and which you hear to be mine now.

but after we had already suffered and been outrageously treated in Philippi, as you know, yet in [the strength of] our God we summoned the courage to proclaim boldly to you the good news of God [regarding salvation] amid great opposition.
