The Lord of hosts is the fighter we need on our side. So the old hymn is for everyone who knows that he is little but believes that God is big. “Jesus loves me, loves me still, though I’m very weak and ill; from his shining throne on high comes to watch me where I lie.” The Lord of hosts watches. He hears. He knows. And He acts. Whatever may fail, “The Lord of hosts is with us; the God of Jacob is our fortress” (Ps. 46:7).
