Charles H. Spurgeon on Psalms 21:3

"For thou preventest him with the blessings of goodness: thou settest a crown of pure gold on his head." The Son of God could not be more ready to ask for the blessings of the divine goodness, than the Father was to give them; and his disposition is the same towards all his adopted sons. Christ, as King and Priest, weareth a crown of glory, represented by the purest and most resplendent of metals —gold. He is pleased to esteem his saints, excelling in different virtues, as the rubies, the sapphires, and the emeralds, which grace and adorn that crown. Who would not be ambitious of obtaining a place therein? —George Horne.
