John 6:63
It is the Holy Spirit who [Note: The Greek word here is "that" instead of "who"] gives life [i.e., understanding the spiritual nature of Jesus' teaching can produce spiritual life]; the flesh is of no value [i.e., understanding Jesus' teaching only in a physical sense makes it worthless]. The words I have spoken to you are [from the] Holy Spirit and [they give] life.

2 Corinthians 2:16
To lost people [we become] a smell of death [i.e., we bring condemnation to people who reject our message]; to saved people [we become] a fragrance of life [i.e., we bring salvation to people who accept our message]. And who is adequate to [accomplish] such tasks?
Hebrews 4:12
For God's word is alive and active and sharper than any double-edged sword. It penetrates [deep enough] even to divide [a person's] soul [from his] spirit, and his joints [from his] bone marrow [Note: This is figurative language describing the penetrating effect of God's word into a person's spiritual, inner being] and is able to judge the thoughts and intentions of a person's heart.
Revelation 11:5
And if anyone wants to harm them, fire will come out of their mouths and consume their enemies. And if anyone tries to harm them, he must be killed in the same way.
