Jesus answered them and said, âTruly, truly, I say to you, you seek Me, not because you saw signs, but because you ate of the loaves and were filled. Do not work for the food which perishes, but for the food which endures to eternal life, which the Son of Man will give to you, for on Him the Father, God, has set His seal.â Therefore they said to Him, âWhat shall we do, so that we may work the works of God?â Jesus answered and said to them, âThis is the work of God, that you believe in Him whom He has sent.â (John 6:25â29)As it does throughout Johnâs gospel, the solemn affirmation amen, amen (truly, truly) introduces an important truth to which Jesus wanted His hearers to pay careful attention. The Lordâs rebuke, âyou seek Me, not because you saw signs, but because you ate of the loaves and were filled,â laid bare their selfish, materialistic hearts. So blinded were they by their superficial desire for food and miracles that they missed the true spiritual significance of Jesusâ person and mission. âThey were moved not by full hearts, but by full belliesâ (Leon Morris, The Gospel According to John, The New International Commentary on the New Testament [Grand Rapids: Eerdmans, 1979], 358). Though they had witnessed the miraculous signs Jesus had performed (v. 14), they failed to grasp the spiritual implications of those miracles. . . .
