"For the Lord God is a sun and shield." Psalm 84:11
Is not the sun made to shine? It is his nature to do so. So it is with the SUN of righteousness; he is made to shine. And does the natural sun lose any of his light by shining? Why, the more he shines, the more light he seems to have. For ages he has shone as brightly as now. His beams were as glorious before we had birth or being, and will be as glorious when the eyes which now see him are mouldering in the dust. Thousands of harvests has he ripened, millions and thousands of millions has he fed; but he shows no sign of exhaustion or decay.
And does Jesus lose anything by communicating his light, life, love, and grace? He is all the more glorified thereby; and the more you look to him as the Sun, that as such he might shine into and upon your soul, the more you glorify him as the Sun of righteousness. When in the morning we throw the shutters back, or draw up the blinds, it is to receive the sun into the dark room. So the more we are enabled by divine grace to throw back the shutters of doubt and fear, and draw up the blinds of unbelief which hang down over the mind, the more we glorify the Lord Jesus by receiving out of his fullness, and grace for grace.
Oh! it is good to be sometimes enabled to look beyond and above doubts, fears, misgivings, and the many things that try the mind. You may pore over your sins and miseries until you fall well-near into despair; you may look back upon your wanderings, inconsistencies, and lack of fruitfulness, until you are almost ready to sink down without hope and die. To do this is to resemble a person wandering in a dark room, tumbling over the furniture, and at last sitting down and saying, "There is no light." If he can but throw back the shutters, the sun will shine into the room.
So we sometimes may sit pondering over our many inconsistencies until we say, "There is no light in my soul; there never was, and there never will be." O to be enabled (when I speak thus, I know well, from soul experience, that it is only God who can do it in us and for us) to throw back the shutters, and look away from those things that so weigh down the mind! Look up, O sinking soul, and see the blessed Sun still shining in the skies of heaven! Why, the very power to do this, the very act of doing so, brings with it a felt blessedness.
How good, also, to be enabled to make use of Christ as a SHIELD! Oh, how often we go to battle without this shield upon our arm! But depend upon it, the Lord would not have provided such a shield for you unless he knew that your enemies were too many for you. Doubt, fear, darkness, despair, the law, the accusations of a guilty conscience, the fiery darts of the devil--how can you fight against these enemies without a shield? Why, you would be like a soldier going out against the foe without either sword or musket, and laying his bosom bare to every weapon, without sword or bayonet in his hand to defend himself.
So, to go into combat against the law; the accusations of a guilty conscience, and a desponding heart, and have no blessed Jesus to hold up as a shield against these deadly foes, would be enough to sink a man into despair. But if he is enabled to make use of the shield that God has provided, and to hold Christ up against a condemning law, a guilty conscience, an accusing devil, and a desponding mind, and say to them all, "Christ has died, and died for me," then he receives into the shield those darts which would otherwise sink into his soul, and then they all fall harmless, because they all fell on the Lord Jesus.
