Rom 7:23

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 2:3-7

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. 5 And also if anyone competes in athletics, he is not crowned unless he competes according to the rules. 6 The hard-working farmer must be first to partake of the crops. 7 Consider what I say, and may the Lord give you understanding in all things. 8 Remember that Jesus Christ, of the seed of David, was raised from the dead according to my gospel,

Heb 12:4

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