My Beloved, God expected Isreal to stay pure when they went to physically combat their enemies. The war we fight today is spiritual, so how do we maintain purity and victory? By remaining in Christ, growing in understanding of what matters, and putting on the armor of light.
Deuteronomy 23:9
9 “When you go to war against your enemies, be sure to stay away from anything that is impure.
Philippians 1:9-11
9 I pray that your love will overflow more and more, and that you will keep on growing in knowledge and understanding.
10 For I want you to understand what really matters, so that you may live pure and blameless lives until the day of Christ’s return.
11 May you always be filled with the fruit of your salvation—the righteous character produced in your life by Jesus Christ—for this will bring much glory and praise to God.
Romans 13:12
12 The night is far spent, the day is at hand: let us therefore cast off the works of darkness, and let us put on the armour of light.
