in the first part of John, we see Jesus performing many miracles and wondrous signs. He heals. He multiplies and feeds. He walk on water.
After He fed the crowd and crossed the water, He was met by the people He had just left. in John 6:25-29, the crowd asks Jesus a very interesting question... and He answers with an even more interesting answer.
Q: "what must we do to do the works God requires?" (vs. 28).
A: Jesus answers, "the work of God is this: to believe in the one He has sent." (vs. 29).
everything starts with belief and faith. my life. my ministry. everything i do.
to do the work of God... i must believe in Jesus. belief is not a one time thing, it is a constant denying of self, crying out to the cross and choosing to believe.
