You know what fascinates me is the fact that God can take our humanity and show His divinity right in the middle of it.
Sometimes I think He shows Himself when we are still hurting... His getting glory doesn't always happen when our lives look amazing to everyone else. Sometimes He gets glory when we fall down, but don't stay down. Of course, He doesn't get glory in the fact that you fell or in what caused you to fall, but He does get glory when you decide to get back up and keep moving with Him.
I don't think we always have to be "spiritual" when God can use us. We don't need to have just been in His glory for 3 hours before He can been seen in our lives--and that amazes me. When our desire is to follow Him in our lives, He takes our daily living and somehow makes it His own. For example, someone could post a Scripture on facebook or some quote they heard, just because they thought it was cool, and later find out it's exactly what someone else needed to make their day. That's just one example of God using us in the middle of our humanity.
Because we are such fragile vessels, God gets more glory when we surrender to Him because He then gets the glory when we are weak, but people somehow see us as strong. Even if no one else knows it, we know that we can't be who we are without Him.
