Review from John

Here are review verses from John:
God is Spirit. Those who God must worship Him in spirit and truth.
Before the world began, there was Word. The Word was with God. The Word was God.
The next day John saw Jesus was coming said to Him that the Lamb of God who takes away sin the world!
Jesus replied, "Don't complain what I tell you."
Jesus said, "I am good shepherd. My sheep knows me and I know my sheep."
Jesus answered, "Stop grumbling among yourselves."
