John 6:28-31

²⁸Then they asked Him, “What must we do to do God’s works?”

²⁹Jesus answered them, “This is God’s work, that you believe in Him who He has sent.”

³⁰Therefore they asked Him, “What sign will You perform then, that we may see it and believe You? What work will You do?

³¹Our ancestors ate the manna in the wilderness. As it’s written, ‘He gave them bread from Heaven to eat.’”
