Luke 1:35
The angel answered, "The Holy Spirit will come upon you and the power of the Highest [i.e., God] will overshadow you. Therefore, the child you carry will be called the holy Son of God.
John 3:6
Whoever is born from human parents is a human being; and whoever is born from the Holy Spirit is a spiritual being.
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].
1 Corinthians 15:39
All flesh is not the same [Note: The word "flesh" here refers to the material composition of matter, and in no way suggests anything sinful, as it does in many other places in Paul's writings]. But mankind has one [kind of] flesh; animals have another kind; birds have another; and fish [still] another.
Ephesians 2:3
All of us [Jews] also once lived among such people, fulfilling the improper cravings of our physical being and doing what our bodies and minds desired. In this natural [unconverted] state we were deserving of [God's] wrath, just like the rest [of mankind].
