John 6:27
King James Version
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.
John 6:27 in context
And when they had found him on the other side of the sea, they said unto him, Rabbi, when camest thou hither?
Jesus answered them and said, Verily, verily, I say unto you, Ye seek me, not because ye saw the miracles, but because ye did eat of the loaves, and were filled.
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.
Then said they unto him, What shall we do, that we might work the works of God?
Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent.
