It's tempting to ask, "who is doing God's work?" But do you know what the work of God actually is? How the Bible defines God's work? In John 6:29 Jesus says, "The work of God is this: to believe in the one he has sent." That's our work: believing.
On the one hand, there's such freedom in this verse. My role on this earth is believing Jesus, trusting Him in things big and small. That's God's job description for my life, and it has such vivid parameters. I like that. But on the other hand, if I lived a life marked by belief, defined by belief, if I just personified complete and utter trust in His good, pleasing and perfect will, I know my life would be different.
It reminds me of the father in Mark 9 who pleads, "I do believe; help me overcome my unbelief!" May we honestly assess where we have unbelief in our lives and then ask God to help us overcome it. I mean when you think about it, your job is on the line. Believing is God's work.
