Read Luke 9:1-17
Here is one of the greatest mysteries: God chooses to do His kingdom work through sinful humans.
It’s one of the greatest mysteries because He doesn’t need us. He could do a much more efficient job Himself. He’s not slowed down by sinful desires and disunity. We may never know why God picks us out before we’re born to be His and to join His mission. But He does.
You are probably familiar with the story of Goldilocks. One chair was too big, another was too little, but she found one that was “just right.”
It’s easy to see our task as “too big,” and our skills or resources as “too little.” We’re waiting for our conditions to be “just right.”
We think, “There’s no way we can reach the world with the Gospel. There’s too much evil, too much hunger, too much suffering…”
It can be even easier to think, “I will never be able to bring my co-worker to Christ, I don’t know enough about the Bible,” or “Serving just requires way more time than I have,” or “Going on that missions trip costs too much money.”
In Luke 9, the disciples were presented with two daunting tasks with next to nothing to work with – or so they might have thought. Jesus sent the disciples out “to proclaim the kingdom of God and to heal.” He told them to “take nothing for your journey.” They probably felt a tad unprepared. A few verses later, 5,000 men (probably 15,000-20,000 people total) needed food and Jesus said, “You feed them.” They had five loaves and two fish. Again – too big of a task, too little to work with.
For the missionary trip, Jesus gave the disciples His Spirit-power to drive demons out and heal diseases. For feeding the multitude, Jesus gave them the food to distribute again and again until everyone was full.
Should we not pack our lunches? Should we not save money? Should we not study the Bible? Is Jesus telling us to be unprepared? No. What He wants is for you to depend on and trust in Him to sustain you – and not just to sustain you, but to make you excel in His kingdom cause!
So even if your circumstances aren’t “just right,” God can use you and He will give you everything you need to be useful!
