Charles H. Spurgeon on Psalms 91:2

My refuge, my fortress, my God. "My refuge." God is our "refuge." He who avails himself of a refuge is one who is forced to fly. It is a quiet retreat from a pursuing enemy. And there are trials, and temptations, and enemies, from which the Christian does best to fly. He cannot resist them. They are too strong for him. His wisdom is to fly into the refuge of the secret place of his God —to rest in the shadow of the Almighty. His "strength is to sit still" there. Isa 30:7. "My fortress." The Psalmist says, moreover, that God is his "fortress." Here the idea is changed —no longer a peaceful, quiet hiding place, but a tower of defence —strong, manifest, ready to meet the attacks of all enemies, ready and able to resist them all. God is a Friend who meets every want in our nature, who can supply every need. So when we are weak and fainting, and unable to meet the brunt of battle, and striving against sin and sorrow and the wrath of man He is our safe, quiet resting place —our fortress also where no harm can reach us, no attack injure us. "My God." Now the Psalmist, as a summing up of all his praises, says "I will say of Him, He is... my God!" Is there any thing omitted in the former part of his declaration? Everything is here —all possible ascription of honour, and glory, and power to Him "as God" —"God over all, blessed for ever, "and of love, reverence, trust, obedience, and filial relation towards him on the part of the Psalmist, as MY God ...when reflecting on the refuge and strength which the Lord has always been to him, and recalling his blessed experiences of sweet communion with God —words fail him. He can only say (but oh, with what expression!) MY GOD! Mary B.M. Duncan.
