David's question is rhetorical — there is no answer because there is no such place. God's Spirit and presence fill everything. This is not a threat but the foundation of ultimate security.
Memory phrase: There is nowhere God is not.
Talk about it: Can you think of a place where God is NOT? (Hint: there isn't one!) How does that make you feel?
Prayer: Lord, wherever I go today — school, home, the park — You are already there. What a comfort that is!
