Do you ever question what is going on in your life? Do you ever question what God is doing?
These verses remind us that Christ knows all things, and that He is always in control. There will be times in our lives when things may not make sense to us. It is during these times that, instead of questioning God, we should trust in Him. He knows all things, even when we do not. God is working all things for His glory and for our benefit, so we should put our full trust in Him, knowing He is in control, even if it seems like we don't know which way is up or down.
