We are a lot like Israel. Too often we doubt God’s promises and are too afraid to do the hard things he’s called us to do. But Caleb and Joshua teach us what true faith looks like. True faith is brave. It trusts that God will keep his promises. If he kept his promise to send the Snake Crusher to rescue us from our sins, we can count on him to keep his other promises. So what do we do when our faith is small? There is a simple prayer we learn from Mark 9:24. It goes like this: “I believe. Help my unbelief.” Even such small faith in a big, promise-keeping God is enough because God is, well, big!
