We Have All Sinned: Why the Bible Says Claiming Otherwise Makes a Person a Liar

A comprehensive Bible study outline exploring the universal reality of human sin, the spiritual deception of denying our fallen nature, and the essential remedy found in the saving name of Jesus Christ through repentance, water baptism, and the infilling of the Holy Spirit.

1. The Universal Reality of Sin

1.1 The Fall and Inherited Depravity

Verses: Romans 5:12; Psalm 51:5
  • Adam's disobedience introduced sin into the entire human race, affecting every descendant.
  • Every person is born with a carnal nature that is inherently inclined toward rebellion against God.

1.2 Scriptural Declaration of Universal Guilt

Verses: Romans 3:23; Ecclesiastes 7:20
  • The Bible declares without exception that all human beings have fallen short of God's glorious standard.
  • There is no one on earth so righteous that they only do good and never sin.

2. The Deception of Self-Righteousness and Denying Sin

2.1 Calling God a Liar

Verses: 1 John 1:8; 1 John 1:10
  • To claim we have no sin is a self-delusion that rejects the absolute truth of God's Word.
  • Asserting that we have not sinned directly contradicts God's testimony, effectively calling Him a liar.

2.2 The Danger of Pharisaical Pride

Verses: Luke 18:11-14; Proverbs 16:5
  • Trusting in one's own righteousness leads to spiritual blindness and ultimate condemnation.
  • God resists the proud who deny their need for mercy but justifies the humble who confess their sins.

3. The Remedy: Repentance and the Saving Name of Jesus

3.1 The Necessity of True Repentance

Verses: Luke 13:3; Acts 17:30
  • Because all have sinned, repentance is an absolute command for everyone to turn away from sin.
  • Repentance involves a complete change of mind and heart, surrendering fully to the one true God.

3.2 Remission of Sins through Jesus' Name

Verses: Acts 2:38; Acts 4:12
  • Water baptism in the name of Jesus Christ is essential for the literal washing away and remission of sins.
  • There is no other name under heaven given among men by which we must be saved.

3.3 Regeneration by the Spirit of God

Verses: John 3:5; Titus 3:5
  • The new birth requires both water and the Spirit to overcome the carnal, sinful nature.
  • Receiving the Holy Spirit empowers the believer to live a holy life, free from the dominion of sin.
