John 6:27-29

Amplified Bible, Classic Edition

²⁷ Stop toiling and doing and producing for the food that perishes and decomposes [in the using], but strive and work and produce rather for the [lasting] food which endures [continually] unto life eternal; the Son of Man will give (furnish) you that, for God the Father has authorized and certified Him and put His seal of endorsement upon Him.

²⁸ They then said, What are we to do, that we may [habitually] be working the works of God? [What are we to do to carry out what God requires?]

²⁹ Jesus replied, This is the work (service) that God asks of you: that you believe in the One Whom He has sent [that you cleave to, trust, rely on, and have faith in His Messenger].
