Isaiah 61:10 I delight greatly in the Lord; my soul rejoices in my God. For he has clothed me with garments of salvation and arrayed me in a robe of his righteousness, as a bridegroom adorns his head like a priest, and as a bride adorns herself with her jewels.
I do love the symbolism used in the Old Testament where descriptions are given which bring our unseen relationship with God into the real world.
When we want to impress someone, we go out of our way to do things which we know they will like; our relationship with God should be no different.
We should go out of our ways to show God how much he means to us and how much we do love Him; yes, He knows, but showing Him is so much more meaningful!
