When we bought our mini van almost 10 years ago - now approaching 140,000 miles - I thought it had a useless feature, this power door that opened and shut with a button. It just came with a van that was a good deal. We were tough enough to open our own doors! Little did I know that it would become one of my favorite features. Toddlers cannot handle heavy van doors, and letting the kids out would have meant endless trips around the car to open the door - this was all avoided with the power door...
When we bought our vacuum cleaner it had this light thing in the front. I thought "That light is useless, why would I pay extra for that." The guy said, lots of people like it. That was not going to be me. Now, 7 years later, I cannot tell you how many Lego pieces have been saved from being sucked into the void by that useless light on the vacuum. Now, I would look for a light on a vacuum for my next purchase.
I have found God is like that too. So often, he has not given what I prayed for, longed for, thought I needed. Instead, God gave me what I actually needed before I even knew I needed it. Oh the joys of being his child, it is good to trust him.
