Trusting God means taking risks. The thought is pretty simple, really. Trusting God means trusting Him, not your ability to understand everything He does. As a pastor, I watch people get confused by this one a lot.
"Where's God right now? What's He doing"
"Pastor, why did He let me experience this?"
"I don't understand what God could be doing in this situation."
We seemed to be convinced that if we can't see what God is doing, then God can't be doing it. But here's the thing: God doesn't have to approve His plan with you. If He did then you would never have to trust Him. You'd simply be approving his plans. And, those are not the same. If you require a comprehension of God plans, you'll never take a risk and step out in faith. Why? Because you'll never do anything that totally depends on God and His character, just on you and your understanding.
What a lame way to live.
Trusting God means taking risks — stepping out in obedience doing things that have unclear outcomes (from our perspectives, at least). If you're afraid of risks, the answer isn't to just manifest some bravery. It's to remind yourself of the nature of God. He's the kind of God who can be trusted with your step of faith.
Jesus said, "Follow me." You may not be sure where you're going, exactly. But, you know you can trust your leader. Take the risk. Trust God.
