Charles H. Spurgeon on Psalms 45:5

Thine arrows. Our King is master of all weapons: he can strike those who are near and those afar off with equal force. Are sharp. Nothing that Jesus does is ill done, he uses no blunted shafts, no pointless darts. In the heart of the King's enemies. Our Captain aims at men's hearts rather than their heads, and he hits them too; point blank are his shots, and they enter deep into the vital part of man's nature. Whether for love or vengeance, Christ never misses aim, and when his arrows stick, they cause a smart not soon forgotten, a wound which only he can heal. Jesus' arrows of conviction are sharp in the quiver of his word, and sharp when on the bow of his ministers, but they are most known to be so when they find a way into careless hearts. They are his arrows, he made them, he shoots them. He makes them sharp, and he makes them enter the heart. May none of us ever fall under the darts of his judgment, for none kill so surely as they. Whereby the people fall under thee. On either side the slain of the Lord are many when Jesus leads on the war. Nations tremble and turn to him when he shoots abroad his truth. Under his power and presence, men are stricken down as though pricked in the heart. There is no standing against the Son of God when his bow of might is in his hands. Terrible will be that hour when his bow shall be made quite naked, and bolts of devouring fire shall be hurled upon his adversaries: then shall princes fall and nations perish.
