Do not follow other gods, the gods of the peoples around you, for the Lord your God, who is among you, is a jealous God. (Deuteronomy 6:14-15a)
There’s a difference between being around and being among. Being around involves aloofness, close in proximity yet not closely involved or invested. Being among is more intimate. It’s more entwined, making it more difficult to tell who is not connected to whom.
That’s the way God is: among. He is invested and involved. He doesn’t come and go. He doesn’t just casually hang out.
I know it doesn’t always feel that way, but our feelings don’t make something so (or not so). We might not be able to fully grasp God’s complete “amongness,” but we can trust Him. He is trustworthy, and He is present.
