Doing the Works of God
In John 6, Jesus teaches the people to "work for the food that endures to eternal life" (6:27). He had just miraculously fed the 5000, then people followed Him looking for some more of this miraculous bread. So, He redirects them to the bread of eternal life.
They ask, "What shall we do, so that we may do the works of God?"
"This is the work of God," Jesus said, "that you believe in Him whom He has sent."
That's it. That's the distilled definition of doing the work of God. All the things we are commanded to do in Christ, from walking in the Truth to making disciples to fighting injustice in the world, this is the nut of it. Believe in the One who was sent.
There's so much behind this, of course. To believe is to trust in, to bet your eternal life on. Believing in the One who was sent necessarily means believing in the One doing the sending. Believing that He was sent means He's of divine origin, but also with a human nature, and that He was sent for a specific and monumental purpose. Real believing results in real actions. And so on.
But simply this: Believe in the One who was sent. Truly do that much, and you are truly doing the works of God.
Just trust. Bank on it. When there's a conflict between the world's message and His message, believe His message. When your selfishness wants A, but you know He wants B, just trust Him. He's the One who was sent.
Sadly, most of those present left Jesus that day (6:66). Peter, however, declared his group was staying with Him, because He has the words of eternal life and He's the Holy One of God (6:68-69). Everyone else was trusting in the things of the world - they were trusting in Him.
