Ever noticed...that, typically, we tend to presume that God needs to come ‘down’ (that God is somehow 'up' — above us…we look to the heavens, to a star, etc)?
Perhaps, this orientation helps us imagine something that we often feel we can’t quite reach here (on this plain). We need help and want or need something to come to us (Oh Come, Oh Come Emmanuel, Your Kingdom Come, etc).
Somehow, the direction of that coming seems important...to us.
