Matthew 10:22-23

Again I just wanted you to see that, so that you will understand that though God is capable of the kind of salvation—the kind of deliverance—that He indicates He will give to His people in Psalm 91, His general advice to His people is to: "flee, get out, get away from the trouble." Even though God could protect one there in the midst of trouble, still God gives this general advice to flee; and I might remind you that David—who was the author of Psalm 3 where he said that he felt safe surrounded by ten thousand people—was fleeing when he wrote it.

This in no way denigrates God, and in no way makes for a "cowardly Christian" when they flee persecution or maybe certain death, demanding that God save them under this horrible circumstance. We have to understand that God places responsibilities on us. I feel certain that, as we take His advice—to flee—He will "open up the mountain" before us so we can go through the path that He makes clear for us.
