Just like we can’t feel the earth spinning on its axis or reeling around the sun, sometimes we don’t know that God is moving in our lives and in world history. The movement is enormous and powerful, but we don’t perceive it.
Sometimes like the movement of the earth, we know about God working, we just can’t really tell. Sometimes we don’t notice because we aren’t looking. Sometimes we don’t notice because God is keeping a secret for now, like a parent wrapping a present unbeknownst to the child. But God is never not doing something behind the scenes. I think He likes weaving intricacies and secrets into things for us to find later.
