John 6:27-29

King James Version

²⁷ Labour not for the meat which perisheth, but for that meat which endureth unto everlasting life, which the Son of man shall give unto you: for him hath God the Father sealed.

²⁸ Then said they unto him, What shall we do, that we might work the works of God?

²⁹ Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent.
