What do you do when you have a genuine need going unmet? It’s one of the great tests, and of course Jesus showed us how to handle it. After His baptism, Jesus was driven into the wilderness by the Holy Spirit. Luke tells us that He fasted for 40 days while the devil tempted Him. At the end of that time, He was literally starving. He needed food, and there was none.
At that moment, the devil attacked. “If you’re the son of God, then turn these stones to bread.”
First the devil attacked his identity: are you really the son of God? Are you sure? If you won’t even use the power to feed yourself when you’re starving, then what’s the point anyway? God’s supposed to be taking care of you here, and all I see is rocks.
Jesus responds with a line from Deuteronomy, when Moses is teaching a new generation to trust God by reminding them of their history. He says “God humbled you, allowed you to suffer hunger, and then fed you with manna that you did not know, nor did your father know, in order to teach you” — and this is the part Jesus quotes — “that man does not live by bread alone, but by every word that comes from God’s mouth.”
You see what Jesus is saying? He’s applying Israel’s experience as the template. First we have a need, and it hurts. The need is real. Then the devil shows up and tempts us not to trust God, to try to do it our own way. And if we fall for it, then we end up trying to eat rocks.
Jesus resisted, and when the temptations were over, angels came and fed Him.
Give in, and you eat rocks; resist, and God gives you manna.
But it’s hard. You know what? Jesus knows firsthand how hard it is; He’s been there. Right this minute He is sitting at the Father’s right hand as your High Priest. He has all the resources of heaven at His disposal, and He is ready to give you the help you need to get through it. He is sympathetic, not condemning. He wants you to ask for help. So ask for help, and He will help you.
