Dead in Sin
"And you hath he quickened, who were dead in trespasses and sins"
- Ephesians 2:1
"Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;)"
- Ephesians 2:5
"And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses"
- Colossians 2:13
What does "dead in sin" mean?
Notice that in all three of the above Biblical references to the phrase "dead in sin" that the solution to spiritual death is God's quickening (or regeneration). This means the concept refers to man's natural state in original sin, apart from the regenerating work of the Holy Spirit. To be unspiritual, dead in sin or "of the flesh", then, refers to man's natural fallen condition of bondage to corruption prior to the intervention of the Holy Spirit. In 1 Corinthinans 2, it teaches us that persons in this state cannot understand spiritual truths when spoken to them, until the Spirit renews them and gives them understanding.
