John Owen wrote these famous words: “Be killing sin or it will be killing you.” Likewise, Charles Spurgeon wrote “If you do not die to sin, you shall die for sin. If you do not slay sin, sin will slay you.”
Great minds think alike, right? This idea was not original to Owen or Spurgeon it came long before them from the pages of Scripture.
Paul commands, “Let not sin therefore reign in your mortal body, to make you obey its passions” (Romans 6:12).
John writes, “Do not love the world or the things in the world” (1 John 2:15).
Peter exhorts, “As obedient children, do not be conformed to the passions of your former ignorance, but as He who called you is holy, you also be holy in all your conduct” (1 Peter 1:14-15).
Time and time again the Bible commands us to flee sin, fight sin, and hate sin. The one who has been saved by grace through faith is now called to live a life that represents Christ well (Colossians 1:10). We are to be holy as He is holy. A call to holiness is a call to wage war on sin.
How can we do this? The good news is that we do not do this alone (Philippians 2:12b-13). God is at work within us to make us more like Him and we can have peace in that. But there is still work to be done.
Here are four practical ways we can fight sin:
It’s so easy to fill our minds with thoughts, plans, dreams, and fantasies that don’t honor Christ. And our actions will follow wherever we let our mind wonder. The Psalmist had come to realize that knowing, meditating, and memorizing Scripture was crucial in fighting sin when he wrote, “I have stored up Your Word in my heart, that I might not sin against You” (Psalm 119:11). Like a squirrel who stores up food to prepare for the long winter, so the Psalmist stores up God’s Word in His heart to prepare him for the long road ahead full of temptation. There are endless benefits of spending time in God’s Word.
Avoid Bad Company
The Bible makes it clear that, “Bad company ruins good morals” (1 Corinthians 15:33). The people you associate with will have great influence on your life. The more time you spend surrounding yourself with morally corrupt people, the more you will become indifferent towards the sin that you so often see and experience. This is exactly the opposite of “do not be conformed” (Romans 12:2) and it will hurt you in your pursuit to fight sin. If you desire to wage war against your sin then you need to have people of godly character in your life. The people you are spending most of your time with should be those who love God and desire His best for you. Striving to have godly people in your life doesn’t mean you can never converse with sinners, it means your closest friends and mentors should be striving for the same thing you are – holiness!
Avoid Tempting Circumstances
In Mark 9 we read, “if your hand causes you to sin, cut it off…And if your foot causes you to sin, cut it off…And if your eye causes you to sin, tear it out…'”(Mark 9:43b-48). These verses can be summed up like this: if there are people, places, things, or situations in your life that frequently cause you to sin then you need to distance yourself from them. You need to do whatever it takes to remove yourself from those vices. If you constantly struggle with purity while surfing the internet then maybe it’s time to get rid of your internet or set up some accountability. If you struggle with drunkenness when you hangout with a certain crowd then maybe its time to stop hanging out with that crowd. If you tend to get really angry and lash out at others while engaging in a particular activity, then perhaps you need to back off of that activity – or “cut it off and tear it out” as Mark tells us. Yes, it will be painful, but this is how serious sin and it’s consequences are. If there are people, places, things, or situations in your life that cause you to frequently sin then you need to remove them from your life, at least for a time, until you get that sin under control.
Jesus in in Matthew 6 tells us to pray in this way, “Our Father…lead us not into temptation, but deliver us from evil” (Matthew 6:9b-13). Later in Matthew 26 Jesus commands His disciples to “Watch and pray that you may not enter into temptation” (Matthew 26:41a). Also in Psalm 141 the Psalmist prays, “Set a guard, O Lord, over my mouth; keep watch over the door of my lips! Do not let my heart incline to any evil, to busy myself with wicked deeds in company with men who work iniquity, and let me not eat of their delicacies!” (Psalm 141:3-4). In all these verses we can see that there is a real correlation between fighting sin and prayer. If you desire to fight sin then you need to be a person of prayer.
Fighting sin is a lifelong battle. Praise God we do not fight sin on our own. God is with us and works in us to make us more like Him, yet we are still called to fight sin ourselves. We do this by meditating on God’s word, spending time with Godly people, avoiding tempting situations, and having an active prayer life asking God to help us fight sin.
