As a believer, do you know what to put on so you will be ready for war? That is the war of the flesh and the Spirit (1 Peter 2:11, James 4:1). The desires of the flesh are against the Spirit and vice versa (Gal. 5:17, Rom. 7:22-23). It's a constant fight. We need to continuously be in the act of "putting off and putting on". Here are a couple of passages that further explain this -
Put off - Sexual immorality, impurity, passion, evil desire, and covetousness, which is idolatry. Anger, wrath, malice, slander, and obscene talk from your mouth. (v.5,8)
Put on - Compassionate hearts, kindness, humility, meekness, and patience. Bearing with one another, forgiving each other, and above all these put on love. (v. 12-14)
Put off - Bitterness, wrath, anger, clamor, slander, and malice.(v.31)
Put on - Kindness, tenderhearted, and forgiving one another. (v. 32)
Basically we fight the flesh and the schemes of the devil by putting on the whole armor of God (Eph 6:10-18). Are you physically fully clothed, but spiritually naked? What's the condition of your heart? God is ultimately concerned about the state of your heart because from it flow the springs of life (Prov 4:23). So each morning, be sure to "dress" your heart!
