Zechariah 2:3-5 describes God as a "wall of fire." In Psalm 125:2 God is describes as "surrounding his people." Psalm 34:7: God "encamps around those who fear him." And Psalm 139:5, one of my favorites: God "hems" me in -- before and behind.
In troubling and uncertain times, I need to know that. I need the security and the safety net that is God's sheltering arms.
