Romans 5:12
Therefore, just as sin came into the world through [the action of] one man [i.e., Adam] and [physical] death through that sin, so [physical] death has spread to all people, because all people have sinned. [Note: This difficult passage (verses 12-21) seems to be saying that the entire human race must experience physical death because of Adam's sin (I Cor. 5:22), which is somehow considered to be everyone's sin. See Murray, pp. 180-187, for a thorough discussion].
2 Corinthians 6:17
Therefore, the Lord says [Isa. 52:11], "You people should leave their company [i.e., unbelievers, verse 14] and separate yourselves from them, and do not touch anything unclean [i.e., their evil practices], and I will welcome you."
Ephesians 2:1
And you [Gentiles] were once [spiritually] dead because of your shortcomings and sins.
Hebrews 9:14
how much more will the blood of Christ, who through the eternal Holy Spirit [or, His eternal Spirit] offered Himself without [moral] blemish to God, cleanse our consciences from deeds which lead to [spiritual] death to serve the living God?
