Why Feeling Bad About Your Sin Is Actually Good News

What do you do when you've done something wrong? Most of us feel bad, right? Unless you're a sociopath, feeling bad about something you've done is common to nearly everyone. But how we respond to that feeling matters and makes a difference in our lives and our faith.

Today, I want to explore one of the most counterintuitive promises Jesus ever made - one that challenges everything our culture tells us about dealing with guilt and shame.

The Upside-Down Promise

In Matthew 5:4, Jesus declares: "Blessed are those who mourn, for they will be comforted."

At first glance, that feels super off. When I imagine the good life - mourning has absolutely no place in it. Usually, mourning and grief mean things are going pretty badly in life. But Jesus is talking about a specific kind of mourning.

Not all grief or mourning is the same; there are three main kinds we can distinguish: Natural mourning (grieving the loss of a loved one), sinful mourning (pining over something God has not given you), and spiritual mourning (sorrow over our sins against God). The kind of mourning Jesus is primarily talking about in this Beatitude is spiritual mourning.

Two Ways to Handle Guilt

While most of us feel bad when we sin, we handle that feeling in different ways. Some feel that heaviness and immediately try to cover it up. They turn to coping mechanisms - pleasure-seeking, numbing agents, substances, distractions. The goal is to escape the feeling.

But Jesus tells us there is a different way. To embrace spiritual mourning. To embrace the grief over sin, which leads to something called conviction.

The apostle Paul understood this well. In 2 Corinthians 7:8-10, he writes: "For the kind of sorrow God wants us to experience leads us away from sin and results in salvation. There's no regret for that kind of sorrow. But worldly sorrow, which lacks repentance, results in spiritual death."

Understanding True Repentance

Conviction is not just a knowledge of what is wrong or a feeling of guilt. Conviction is a recognition in your soul that your sin is abhorrent to God. It's an understanding of how deeply our sin dishonors God.

The Heidelberg Catechism, written by German theologian Zacharius Ursinus in the 1500s, defines repentance as "the dying of the old nature and the coming to life of the new." This helps us understand what Jesus means when he promises comfort to those who mourn.

So where the world would have you cover up the bad feelings with temporary pleasures and distract yourself from what is wrong, Jesus would have you embrace the sorrow and receive life change that brings true comfort and joy.

David's Story: From Giant-Slayer to Repentant King

This principle comes alive in the story of King David - the overlooked youngest son who became a giant-slayer and eventually king. David was known for having a heart after God, but that's exactly why his story matters for us today, because the same David who defeated giants is also the David who fell.

In 2 Samuel 11, we find David's infamous affair with Bathsheba, the wife of Uriah, one of his military chiefs. Not only did David commit adultery, but when Bathsheba became pregnant, he orchestrated Uriah's death in battle to cover up his sin. God was not pleased - David had broken both the sixth commandment (thou shalt not kill) and the seventh (thou shalt not commit adultery).

When the prophet Nathan confronted David through a parable about a rich man stealing a poor man's only lamb, David was furious at the injustice. Then Nathan delivered the crushing words: "You are that man!" (2 Samuel 12:7).

What Spiritual Mourning Looks Like

David's response reveals what true spiritual mourning looks like. In Psalm 51, his psalm of repentance, David writes: "Have mercy on me, O God, because of your unfailing love... For I recognize my rebellion; it haunts me day and night. Against you, and you alone, have I sinned; I have done what is evil in your sight" (Psalm 51:1-4).

Charles Spurgeon explained it this way: "[David] is sick of his sin; his loudest outcries are against the evil of his transgression, and not against the painful consequences of it. When we deal seriously with our sin, God will deal gently with us."

David expresses heartbreak at what he has done, at the depravity of his sin and his rebellion against God. And it's in this mourning that he asks God for his joy back.

The Promise of Comfort

How can David ask for joy after doing something so horrible? Because of grace. Though he faced consequences for his sin, he also found restored intimacy with the Lord through his repentance.

The message today is not to feel worse about your sin; it's to feel rightly about your sin, then you will be comforted. Romans 6:23 tells us "the wages of sin is death," and God declares in Zechariah 8:17, "I hate all this." God hates sin because it's rebellion against Him.

But Jesus doesn't leave us with just mourning. Through the line of David, our joy of salvation is promised. Jesus, a descendant of David, came to live the perfect sinless life in our place. When the weight of our sin is heavy, we can know that God is at peace with us through the sacrifice of Jesus Christ, who has taken the punishment in our place.

Putting It Into Practice

Practically speaking, mourning over our sin looks like not hiding from the bad feeling, but letting it spur us to change. Coming up with ways that we can avoid giving in to that sin again, maybe even praying Psalm 51. Expressing our distress and asking the Lord for comfort.

Where the world accepts and celebrates sin, Jesus tells us to mourn. To see the evil in ourselves and in our world and grieve that something so vile to God is commonplace. Because those who mourn over their sin will find heartfelt joy in Christ and delight in His good works.

Remember this promise: the same place your sin feels the heaviest is the place God's grace meets you the deepest.
