Perhaps where we're at now is draining us of the energy we need to get through. When we're in a desperate place, let's never forget that God's arms are around us, even when we can't see light at the end of the tunnel.
Let's head to John 6:1-15, where Jesus and his disciples are faced with a crowd of five thousand. Five loaves and two fish aren't exactly the lunch this massive crowd was hoping for. The disciple Andrew's response reflects exactly how we can feel when we look down at the minimal supplies we have. In John 6:9 NLT he says, 'What good is that with this huge crowd?' Who can blame him? It's natural. But that's just it, it's natural.
To look at our situation through God's eyes is to rely on his long history of supernatural faithfulness. The Bible's full of unchangeable situations. Imagine how the early Church felt about Saul, the most violent opponent of Christians. No one would be blamed for thinking Saul would never turn to Jesus; he wanted God's people chained up (Acts 9:2). But, a few verses later, he's with the disciples serving Jesus.
God wants to show us how he can, and will, blow the natural, pessimistic responses we have, out of the water.
So what now? Given up on something you hoped might work out? Pray, then take another look at it. Maybe God will confirm you should leave it, or maybe he wants you to look at it from his point of view. See what happens.
