The Cancer of Sin (Mark 9:42-50)

Posted on Updated on

With regard to sin, take drastic action! – Jesus  

When it comes to certain things in life, what is needed is decisive drastic action. Time wasted deliberating is counter-productive if not life-threatening.

A few years back, in quick succession, I had a lump on my back that my General Practitioner didn’t like the look of, and then one on my cheek that was reddish and would bleed with the slightest touch and didn’t respond to the non-invasive treatments prescribed.  

As you know, cancer is a horrible result of the curse that has devasted so many people’s lives and brought so much heartache. And because of this, cancer is not to be messed with and so in both instances with the advice from the Doctor’s involved it was easy to decide to undergo surgery to cut out what turned out to be cancerous tissue on both my back and face.  

Operations and surgery are not pleasant experiences, and my face and back will forever show the scars. But that is a small price to pay for a cancer-free body. No one in their right mind hearing that they had cancerous growth that can be removed surgically would say; ‘I’ll just see how it develops Doc…’

In my case, drastic action was necessary, temporarily painful invasive surgery was prescribed, but it was worth it 1000 times over. How many people have much more serious cancer in their body who would love to know that their cancer could be surgically removed.

In our passage today, Jesus is the great Surgeon. Jesus knows that sin is not something to be messed around with, not something to be treated lightly. Drastic intentional invasive action is needed for sin’s deadly progression to be halted.

Now let’s be clear, in Mark 9:42-50, Jesus is not advocating body mutilation as a solution for sin. Of all people, Jesus knows that the problem with sin is not external but rather a heart issue, a fallen humanity issue that can’t be fixed by us. Sin can’t be dealt with by removing external body parts!

Jesus knows this because, after all, this is why Jesus left heaven and came to earth. To do what we could not do ourselves, to take the drastic action that was needed to halt sin’s deadly progression in our lives.  

So what is Jesus teaching in Mark 9:42-50?

I think we can understand Jesus’ teaching on at least two levels.

  1. Jesus is teaching that sin is serious and that if one sees the seriousness of sin, then one will see that drastic action is entirely reasonable. Don’t play around with sin thinking you’ll be ok, thinking you’ll be the exception! So if you are a Christ-follower but you know of some sin or compromise that you have in your life right now – treat it like cancer.  Cut it out!  Delaying only worsens the prognosis and allows the sin to spread impacting more areas of your life and the lives of others. So where you know you have sin, take drastic action, stop, repent to God, change your life patterns, change your friends if you have to, change places you frequent, speak to a fellow Christ-follower and confess or speak to a leader in the church, but do it now, don’t delay.
  2. Know your limitations!  If you don’t know Jesus as your LORD and Saviour yet, know this – you can’t deal with sin on your own. That is why Jesus came, to live the life you and I could never hope to live and to die in our place for our sin and shame so that He could offer us forgiveness for our sins and redeem us from slavery to sin, Satan and ultimately death and hell. So put your trust in Jesus today, ask Him to forgive you of your sin and to exchange your shame and sin for His glorious love and forgiveness. In this passage, Jesus talks plainly, chillingly about hell. Hell is real, and hell is the only destination for those outside of true faith in Jesus Christ. Randy Alcorn said; “No man can get out of hell, but each man can keep out of it.” How? By acknowledging and repenting of the cancerous sin that is inside of us and asking Jesus to do what we could not do. Jesus took drastic action on our behalf; Jesus didn’t just have the cancer of sin cut out of Him; Jesus sacrificed His whole life to give you a sin-free eternal life. So put your trust in Him alone!

No one would turn to the Doctor who has just diagnosed them as having cancer and charge them of being unloving and harsh. With the terrible realities of a disease like cancer, honesty, facts & potential drastic solutions is the language of love.

Some would read this passage about the seriousness of sin and the reality of hell and baulk at Jesus’ words thinking; ‘I don’t like what Jesus said!’ But love speaks frankly about life-threatening situations, and this is what Jesus is doing here, loving us by speaking truthfully about the certainty of sins progression if left unchecked.

Thank You, Jesus, for loving us enough, to tell the truth about sin and hell and for loving us enough not just to diagnose our sin problem but to choose to take the drastic action you did to die in our place for our sin, for you to suffer so that we could be set free!

Amazing grace, how sweet the sound, that saved a wretch like me. Thank you, Jesus.
