I’ve written before about how God doesn’t fit into a box you’ve made for Him (God in a Box), and about the universe being like a box (Outside the Box). Sometimes it helps to think of God being outside of the box and reaching in, but God is omnipresent so it’s important to remember He’s inside the box at the same time!
While it is important to think outside the box, you don’t have to find the edge of the box or look outside the box to find God.
