War is not a metaphor for many things but it's definitely one for fighting sin. Sin is a constant battle: our human nature gravitates toward sin while our spiritual calling demands holiness. We battle gods of many kinds. For example, the god of money believing that our toys and possessions give human life meaning. We battle the god of sex and the pursuit of God's great gift outside of a committed marriage. Those are two powerful human influences and require supernatural effort.

Don't Be Passive In The Battle.
Passive soldiers get defeated, and a lot of men are getting defeated by fleshly desires. Why? They don't believe they have the strength to stand up and declare "No!" They are shamed by their past mistakes or they are just apathetic and believe their efforts will make no difference. But our effort makes a difference. When we engage the battle great things happen.

If you have watched modern day soldiers get suited up for battle, you know how much they prepare for the battle they face. They gear up with helmets; flack jackets; ammunition; boots; night vision goggles; earpieces and weaponry and all the additional gear that goes in the packs. It is pretty impressive. Yet, we go into our day with little thought about the battles we will fight that day or the defensive and offensive gear that we need spiritually in order to fight our battles. It is no wonder we are defeated by sin. This is because passivity never works when we come to battle.

Go Into Battle Prepared.
Each of us knows where we're most vulnerable. Don't go into a new day without a plan for how you will handle your vulnerabilities. Not to do so is stupidity. First, devise a plan each day on how you will prepare for your days battle with your sin. Second, engage the weapon of prayer during the day asking God to help you deter and battle your sinful tendencies. Third, build a band of brothers and be candid with them who can encourage you and hold you accountable. Fourth, study Ephesians 6 regarding the armor of God and dig in deep in making better preparation in your heart and mind.

Those who downplay sin get defeated by it and lose the battle. Those who take it seriously and prepare are ready for victory through the Spirit. Take sin lightly and you will pay a terrible price ultimately. Take it seriously and you will prevail, or better God through you. Remember: "sin is crouching at your door; it desires to have you, but you must master it."
