I have been reading a chapter a day out of my Bible from when I was a little girl... it is "the Picture Bible". Anyways, today was when Nicodemus meets with Jesus and Jesus is explaining what it is like to be "born again". Nicodemus doesn't understand so Jesus explains that just like you cannot see air, you can see how it moves the tree leaves and compares that to the Spirit of God, which you cannot see but you can see His effects on a persons heart.
Then we read the science text out of God's Wonderful Works and... haha, it said just what Jesus had said. We cannot see air but we can see what the wind can do. DS perked up and drew the conclusion on his own.
Just thought it was cute and totally not planned. It just worked.
