Charles H. Spurgeon on Psalms 21:2

"Thou hast given him his heart's desire." That desire he ardently pursued when he was on earth, both by his prayer, his actions, and his suffering; he manifested that his heart longed to redeem his people, and now in heaven he has his desire granted him, for he sees his beloved coming to be with him where he is. The desires of the Lord Jesus were from his heart, and the Lord heard them; if our hearts are right with God, he will in our case also "fulfil the desires of them that fear him." "And hast not withholden the request of his lips." What is in the well of the heart is sure to come up in the bucket of the lips, and those are the only true prayers where the heart's desire is first, and the lip's request follows after. Jesus prayed vocally as well as mentally; speech is a great assistance to thought. Some of us feel that even when alone we find it easier to collect our thoughts when we can pray aloud. The requests of the Saviour were not withheld. He was and still is a prevailing Pleader. Our Advocate on high returns not empty from the throne of grace. He asked for his elect in the eternal council-chamber, he asked for blessings for them here, he asked for glory for them hereafter, and his requests have speeded. He is ready to ask for us at the mercy-seat. Have we not at this hour some desire to send up to his Father by him? Let us not be slack to use our willing, loving, all-prevailing Intercessor. "Selah." Here a pause is very properly inserted that we may admire the blessed success of the king's prayers, and that we may prepare our own requests which may be presented through him. If we had a few more quiet rests, a few more Selahs in our public worship, it might be profitable.
