Rom. 7:23

23 But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.

2 Cor. 10:3-6

3 For though we walk in the flesh, we do not war according to the flesh. 4 For the weapons of our warfare [are] not carnal but mighty in God for pulling down strongholds, 5 casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ, 6 and being ready to punish all disobedience when your obedience is fulfilled.

2 Tim. 1:18

18 This charge I commit to you, son Timothy, according to the prophecies previously made concerning you, that by them you may wage the good warfare,

2 Tim. 2:3-4

3 You therefore must endure hardship as a good soldier of Jesus Christ. 4 No one engaged in warfare entangles himself with the affairs of [this] life, that he may please him who enlisted him as a soldier.

Heb. 12:4

4 You have not yet resisted to bloodshed, striving against sin.
