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." - John 6:28-29
Either work is easy or belief is hard work.
I am going to presume that both are true.
Belief-work is what produces lasting satisfaction in our lives. This is the preface to Jesus' teachings on the bread of life. Because people are hungering for more, Jesus is addressing that hunger and providing Himself as the source of "food that endures to eternal life."
So far, they have labored with frustration and only temporary satisfaction. There is a need in every human to produce something of lasting value. Futility is the fruit of meaningless work. Jesus offers more.
Belief is not a passive thing. The word for "believe here is "pisteuhte", "to keep on believing." I have always been intrigued that the root of the word is used for our modern word, "pistol." Pistols launch projectiles into open space and belief launches our lives and efforts to a place beyond ourselves.
The work of God is to believe. Once we accept that, we can begin to learn what it means to believe. We can be taught by God what the implications of living faith really are. We can begin to be shaped by our believes as they take shape within in us.
As a starting point (as well as an ending point), Jesus gives us focus, to believe in Him whom the Father has sent.
