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].
Romans 6:23
For the wages for sinning is [spiritual] death, but God's free gift is never ending life in [fellowship with] Christ Jesus our Lord.
1 Corinthians 15:21-22
For since death happened to a man [i.e., Adam], the resurrection from the dead also happened to a man [i.e., Christ].
James 1:15
Then, when the evil desire has conceived, it gives birth to sin. And when sin is fully grown, it produces [spiritual] death.
Romans 3:23
for everyone has sinned and falls short of God's glory [i.e., His approval, or His perfect character].
Romans 5:19
For just as many people [i.e., all mankind] were considered [by God] to be sinners [and thus to suffer physical death] through the disobedience of the one man [i.e., Adam]; even so, many people [i.e., all believing mankind] will be considered right with God [and thus live again] through the obedience of the one man [i.e., Christ].
Romans 5:14-17
Yet [physical] death ruled [over mankind] from the time of Adam to Moses, even over those people who had not sinned the way Adam did. [Now] Adam prefigured the coming of Jesus.
Romans 5:21
This was so that just as sin ruled [over mankind], causing [physical] death, even so God's unearned favor would rule [over mankind], providing [them with] righteousness, and leading to never ending life through Jesus Christ our Lord.
James 3:2
For we all make mistakes in many areas [of life]. If anyone does not make a mistake in what he says, he is a perfect person, capable of keeping a tight rein on his whole life also.
1 John 1:8-10
If we claim to have no sinful practices [in our lives], we are self-deceived and are not being truthful about the matter.
Revelation 20:14-15
Then death and the unseen place of departed spirits were thrown into the lake of fire [i.e., after their spirits were reunited with some kind of a body]. This lake of fire is the second death.
