The Mortification of Sin
Website Editor • May 6, 2020
Matthew 5:27-30
The stakes are high in the battle against sin. Kill it, or it will kill you.
In Matthew 5, Jesus teaches that we must go to extreme measures to expel sin from our lives. The example He gives is, "if your right eye causes you to sin, tear it out and throw it away. For it is better that you lose one of your members than that your whole body be thrown into hell."
EXTREME.
Now, Jesus is obviously offering a bit of hyperbole here, but his point is clear: take sin seriously. Hate it. Do everything in your power to rid yourself of it. The cost of sin is eternity in hell.
The first step in our battle plan is to HATE sin.
The commandment Jesus addresses in this passage is to not commit adultery, but he takes the sin a step further and says, "everyone who looks at a woman with lustful intent has already committed adultery with her in his heart." The righteousness God requires of us is much bigger than just the surface sin. Jesus is not asking "are you keeping the rules", but, "do you abhor sin?"
If you abhor sin, you can fight it.
Romans 8:13 says, "For if you live according to the flesh you will die, but if by the Spirit you put to death the deeds of the body, you will live."
This verse is such an encouragement because it tells us we can indeed put sin to death.
So, how do we fight it?
1. We must fight consistently.
Just because you rid your lawn of weeds, doesn't mean they won't come back. We must continually work on this and petition God for victory.
2. We must fight combatively.
We must be savage, barbaric, violent, ruthless, and creative. We must make the mortification of sin our daily work.
In the fight against lust, for example:
We can eliminate sources of temptation
such as: TV shows, social media, computer, smart phones, etc. -- it's impossible to eliminate everything, but the elimination of SOMETHING is certainly better than doing nothing.
We can also get help by being open about our struggles. Bring community into your battle so they can fight alongside you. Seek a mentor ahead of you in this, so they can pray for you and equip you with wisdom.
We can equip ourselves for battle. Memorize scripture; pray and think about the battle daily; evaluate failures; read books about it.

3. We must fight by the Spirit.
We must acknowledge that we are utterly dependent on Him and that we have no strength of our own. If you are in Christ, He has given you a new heart that seeks Him. While this life is truly a battle, there is a finish line.
"Therefore, since we are surrounded by so great a cloud of witnesses, let us also lay aside every weight, and sin which clings so closely, and let us run with endurance the race that is set before us, looking to Jesus, the founder and perfecter of our faith, who for the joy that was set before Him endured the cross, despising the shame, and is seated at the right hand of the throne of God."
-- Hebrews 12:1-2
The reward is great for those who run the race to the end.

Notes from Lance Shumake's sermon on Sunday, June 22, 2025. Sermon text: 1 Peter 4:12-19 We shouldn’t be surprised when we encounter suffering John 15:18–20 [18] “If the world hates you, know that it has hated me before it hated you. [19] If you were of the world, the world would love you as its own; but because you are not of the world, but I chose you out of the world, therefore the world hates you. [20] Remember the word that I said to you: ‘A servant is not greater than his master.’ If they persecuted me, they will also persecute you. 2 Timothy 3:12 Indeed, all who desire to live a godly life in Christ Jesus will be persecuted We can rejoice knowing we are sharing in Christ’s suffering Matthew 5:11–12 [11] “Blessed are you when others revile you and persecute you and utter all kinds of evil against you falsely on my account. [12] Rejoice and be glad, for your reward is great in heaven, for so they persecuted the prophets who were before you. We don’t bring glory to God when we suffer for doing wrong We should choose to glorify God instead of being ashamed We should live in light of the coming judgment of God “Peter shows the meaning of our suffering from two sides. First, our suffering for Christ finds its significance in Christ’s suffering for us. We share now in suffering for him as we shall one day share in glory with him (4:13; 5:1). Secondly, our suffering does not destroy us, but purifies us. The fire of God’s judgment that we endure is not the fire of wrath that will consume the unbelieving.” —Edmund P. Clowney, The Message of 1 Peter We can entrust our souls to our faithful Creator Discipleship Questions: Why is it our tendency to be surprised when we encounter suffering? What are some reasons for rejoicing when you encounter suffering? Why is it so tempting to classify all suffering as persecution, even when we suffer for doing wrong? How can you resist feeling ashamed when you suffer for being a Christian? How do you think God uses suffering to purify His church? How does entrusting your soul to God help you find hope?

Notes from Scott Sutton's sermon on Sunday, June 15, 2025. Sermon text: 1 Peter 4:7-11 Would you know if your prayers were hindered? How would you know? What causes prayers to be more fruitful? What causes prayers to be interrupted? What hinders our prayers? Not living with your spouse in an understanding way A lack of sober mindedness and self-control Hindered prayers hurt our relationships A lack of self-control… letting your flesh rule you will never result in healthy relationships. A lack of sober mindedness… letting your thoughts rule you will never result in healthy relationships. Self-control and sober minded prayer are those inward things that result in outward expressions. They ready us to set our focus and affections on other people. Application: Keep loving one another earnestly Aim to cover a multitude of sins Make your home available to others Make your gifts available to others Speaking Serving Discipleship Questions: Have you ever become aware that your prayers are hindered? How did you know? What are some practical steps that we can take to strengthen our prayer lives? How do hindered prayers hurt our relationships? How do unhindered prayers strengthen our relationships? What are some practical ways that we can aim to cover a multitude of sins? Define at least 2 practical ways in which you will make your home and your gifts available to others this week. How has your life been impacted by others who have made their homes and their gifts available to you?

Notes from Ky Martin's sermon on Sunday, June 8, 2025. Sermon text: 1 Peter 4:1-6 Prepare to suffer Is. 50:6-8a I gave my back to those who strike, and my cheeks to those who pull out the beard; I hid not my face from disgrace and spitting. 7 But the Lord God helps me; therefore I have not been disgraced; therefore I have set my face like a flint, and I know that I shall not be put to shame. 8 He who vindicates me is near. The martial language indicates that discipline and grit are needed to live the Christian life, particularly in view of the suffering believers encounter. -Thomas R. Schreiner Some people won’t like you if you follow Jesus When a culture abandons biblical standards, when extramarital sex, cohabitation, and birth outside of marriage become normal, people attack the church for its moral snobbery and judgmentalism. Peter warns us that if we do take a stand, we need to expect slander, not applause. -Daniel M. Dorian This is one of the hardest things a new Christian has to face. Your friends liked you because you shared in “the same flood of debauchery.” It seemed great fun at times, but then you came to embrace Christ… But your friends have not… They will be surprised when you say “No.” -Juan Sanchez. Keep an eternal perspective Our outcome is glorious Suffering is good for us Let’s remember that suffering accomplishes God’s purposes. It exposes what or whom we are trusting (1 Peter 1:6–7). - Juan Sanchez Ecc. 7:2 It is better to go to the house of mourning than to go to the house of feasting, for this is the end of all mankind, and the living will lay it to heart. Discipleship Questions: Verse 1 tell us to arm ourselves by thinking as Christ did about suffering. How did Christ arm himself for and against sufferings? What does it look like for us to do that? Have you ever lost friendships (or had them change) because you were following Jesus? Do you fear that we (or our kids) will experience greater persecution in the future? If yes, how should we handle that fear?
