Walking in the Light

by | Sep 20, 2026 | Mt Pleasant Sermons

Bible Study

Don’t just take our word for it . . . take His! We would encourage you to spend time examining the following Scriptures that shaped this sermon: 1 John 1:5-10, John 3:16-21, Rom 1:18-25, James 5:13-18.

I. God’s Character: God Is Light (1:5)

A. Sin is understood in light of who God is

  • “God is light, and in him is no darkness at all.”
  • God’s moral perfection: Truth, Goodness, Purity, Justice, No hidden darkness

B. Sin distorts our purpose

  • We were created to reflect God’s glory.
  • Illustration: a mirror reflecting light.
    • Tarnished mirror = sin corrupting God’s image.
    • Turned mirror = idolatry and self-centeredness.
  • Sin is anything that distorts or redirects God’s light shining in and through us.

C. Sin remains a reality for believers

  • Christians have a new identity.
  • Yet the possibility of sin remains.
  • “If we say we have no sin, we deceive ourselves.” (v. 8)

II. God’s Provision: Jesus Cleanses Sin (1:7; 1:9; 2:1–2)

A. The gospel’s repeated refrain

  • Sin is real…
  • But God has provided a Savior.

B. Jesus does what we cannot do

  • “The blood of Jesus… cleanses us from all sin.”
  • We cannot cleanse ourselves.
  • Christ’s cross is God’s answer to sin.

C. The tragedy of denying sin

  • It separates us from reality.
  • It also keeps us from experiencing forgiveness.
  • The joy of being fully known and fully loved is found only through Christ.

III. Our Response: Walk in the Light Through Confession (1:9)

A. What confession is not

  • Not the basis of forgiveness.
  • Not obsessive self-analysis.
  • We confess from acceptance, not for acceptance.

B. Practice confession corporately

  • General confession in worship.
  • Cultivates humility and dependence on God.

C. Practice confession privately

  • Invite the Spirit’s examination.
  • Psalm 139:23–24.
  • Not self-condemnation, but repentance and renewal.

D. Practice confession relationally

  • “Fellowship with one another” (v. 7).
  • “Confess your sins to one another” (James 5:16).
  • Need a few trusted believers for Honesty, Accountability, Encouragement, and Gospel reassurance

E. The atmosphere of confession is grace

  • The goal is not shame.
  • The goal is walking in the light together.
  • “The blood of Jesus cleanses us from all sin.”

Discussion Questions

  1. Do you agree that there is a tendency in our culture to diminish or deny the reality of sin? If you agree, what are some examples that you have noticed?
  2. Why is understanding God’s character important for a right understanding of sin? Also, how does the call to reflect God’s image also help us understand sin?
  3. If I am a Christian, should I still call myself a sinner?
  4. What role does confession play in your life currently?
  5. Is it possible for a Christian to totally conquer sin in this life?
