The Spirit gives life; the flesh counts for nothing. The words I have spoken to you – they are full of the Spirit and life. (NIV)

It is the Spirit Who gives life [He is the Life-giver]; the flesh conveys no benefit whatever [there is no profit in it]. The words (truths) that I have been speaking to you are spirit and life. (AMP)

It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life. (KJV)
