To want to know the reasoning behind why things are the way they are is human nature. We have numerous professions dedicated to it, spent countless hours in school learning about the 'why' behind things in subjects like science and history. You'll even find that inquisitive toddlers can't stop asking the question.
There are the easy questions, like- Why do we need to eat? Or why is it important to exercise? Questions that can easily be answered. But there are questions that even now, the smartest person on earth can't wrap their head around.
This generation has information at their fingertips. We are the most informed bunch of youngsters that have ever lived. But we still have a lot of questions. And it's good to be inquisitive. But sometimes needing to know 'why' can be dangerous.. it might even cost us our faith.
Let me explain. I think sometimes we feel that God owes us an explanation. "Why did you let that happen to me God?", "Why did you place me in this position?".
He is GOD. He is SOVEREIGN. In His grace, sure, sometimes God reveals to us the reason behind his actions. But he doesn't owe us anything.
And when we ask the questions like that, I think we have to ask ourselves what we are really questioning. Are we questioning God's character? His faithfulness? Who He says He is? Because that is dangerous territory to get into.
When God speaks, and asks us to do something that just seems ridiculous at the time, or when bad things happen, it's natural to want an explanation. But when we ask and don't get an answer, I hope it doesn't cause us to stumble. Because he is God. Trust in who God says He is. You would follow the instruction (no questions asked), or accept the ruling of someone whose character you had total faith in. Because you know they would never purposely do anything to harm you.
So trust in God. Even if you don't know why. That sounds something like faith to me.
