John 6:63 It is the Spirit who gives life; the flesh profits nothing. The words that I speak to you are spirit, and they are life.
Without our spirits our bodies are but lumps of flesh and bone; they may be remarkable but they would be lifeless without our spirits.
Though we may live and be full of life on earth, we are dead to God unless we have His Spirit which He gives to us.
When we are born in the Spirit of God we gain a new life with Him toward which the mortal body we live in profits nothing.
Jesus wants us all to have the Holy Spirit so that we can enjoy life to the fullest with Him.
