Labor Not For The Food Which Perishes

John 6:25-27

25  And when they had found him on the other side of the sea, they said unto him, Rabbi, when came you here?
26  Jesus answered them and said, Verily, verily, I say unto you, You seek me, not because you saw the miracles, but because you did eat of the loaves, and were filled.
27  Labour not for the meat which perishes, but for that meat which endures unto everlasting life, which the Son of man shall give unto you: for him has God the Father sealed.
