Charles H. Spurgeon on Psalms 40:16

Let all those that seek thee, rejoice and be glad in thee. We have done with Ebal and turn to Gerizim. Here our Lord pronounces benedictions on his people. Note who the blessed objects of his petition are: not all men, but some men, "I pray for them, I pray not for the world." He pleads for seekers: the lowest in the kingdom, the babes of the family; those who have true desires, longing prayers, and consistent endeavours after God. Let seeking souls pluck up heart when they hear of this. What riches of grace, that in his bitterest hour Jesus should remember the lambs of the flock! And what does he entreat for them? it is that they may be doubly glad, intensely happy, emphatically joyful, for such the repetition of terms implies. Jesus would have all seekers made happy, by finding what they seek after, and by winning peace through his grief. As deep as were his sorrows, so high would he have their joys. He groaned that we might sing, and was covered with a bloody sweat that we might be anointed with the oil of gladness. Let such as love thy salvation say continually, The Lord be magnified. Another result of the Redeemer's passion is the promotion of the glory of God by those who gratefully delight in his salvation. Our Lord's desire should be our directory; we love with all our hearts his great salvation, let us then, with all our tongues proclaim the glory of God which is resplendent therein. Never let his praises cease. As the heart is warm with gladness let it incite the tongue to perpetual praise. If we cannot do what we would for the spread of the kingdom, at least let us desire and pray for it. Be it ours to make God's glory the chief end of every breath and pulse. The suffering Redeemer regarded the consecration of his people to the service of heaven as a grand result of his atoning death; it is the joy which was set before him; that God is glorified as the reward of the Saviour's travail.
