31 Days of Purity: Confess Your Sin

Through the month of March, I am inviting you to 31 Days of Purity—thirty-one days of thinking about and praying for sexual purity. Each day features a short passage of Scripture, a reflection on that passage, and a brief prayer. Here is day five:

Blessed is the one whose transgression is forgiven,
whose sin is covered.
Blessed is the man against whom the Lord counts no iniquity,
and in whose spirit there is no deceit.

For when I kept silent, my bones wasted away
through my groaning all day long.
For day and night your hand was heavy upon me;
my strength was dried up as by the heat of summer.

I acknowledged my sin to you,
and I did not cover my iniquity;
I said, “I will confess my transgressions to the LORD”
and you forgave the iniquity of my sin.

(Psalm 32:1-5)

It took God’s heavy hand of discipline for David to understand a simple truth: we need to confess our sin to God. We do not confess our sin so God will know what we have done—he already knows every deed, and even every thought and intention of the heart. We confess that sin for our own benefit, to acknowledge it before him and to seek his forgiveness. Though God assures us that at the moment of our salvation all of our sin is forgiven—past, present, future—still we need to confess our sin before the Lord as an acknowledgement that every sin is ultimately directed at him, that every sin stems from a lack of delight in what he promises, and that we have knowingly, willingly, damaged our fellowship with him.

Do you confess your sin before the Lord? A mumbled “Forgive me” once a week will not do. Confess your sin—even that shameful sexual sin—honestly, humbly and thoroughly. God knows it all, but he will hear your confession and, because of what Christ has done, it will be his joy to offer full forgiveness and reconciliation. Here is his promise to you: “If you confess your sins, I am faithful and just to forgive you your sins and to cleanse you from all unrighteousness” (1 John 1:9).

Father, I am a sinner. “You make known to me the path of life; in your presence there is fullness of joy; at your right hand are pleasures forevermore” (Psalm 16:11). And still, far too often, I seek pleasure in what you forbid. I allow myself to believe that your pleasures are inadequate and that something or someone holds out what I need or what I deserve. I confess my sin to you. I confess that my heart has desired what you say is evil; my mind has pondered what you say is sinful; my eyes have looked with lust instead of love. I confess my sin, I acknowledge it to you, and I joyfully receive your forgiveness.

What Now? Consider joining our 31 Days of Purity Facebook group. It is optional, but you will find it a good place to go for discussion and encouragement. (Note: that Facebook group is for men only; here is one for Women Supporting Men).

    Do You Board First or Last?

    There are some travelers who like to board an airplane at the earliest possible moment. There are others who prefer to board at the last. Some rush the gate the very second the gate agents announce that boarding has commenced, while some linger until they have sounded the final call.

    Our culture lacks any coherent, unifying worldview. We’ve moved on from post-truth postmodernism to “Live your truth” metamodernism, where good vibes matter more than consistent ideas. In this world, few see the conflict between “trans-affirming” and “pro-woman.” And the same person using mushrooms to aid spiritual “connection” tells us to “trust the science” about human…
