John 6:27-29

27But don’t be so concerned about perishable things like food. Spend your energy seeking the eternal life that the Son of Man can give you. For God the Father has given me the seal of his approval.”

28They replied, “We want to perform God’s works, too. What should we do?”

29Jesus told them, “This is the only work God wants from you: Believe in the one he has sent.”
