Charles H. Spurgeon on Psalms 99:8

Thou answeredst them... forgavest them. Oh, the blessed assurance that nothing can disturb our standing in the covenant. Answer and forgiveness are certain, though vengeance is taken of our inventions. How every word and expression here seems to go right to our hearts! The very designation of our sins and punishments is so true. Yet, withal, we are not shut out from God. We are able to speak to, and to hear him; we receive what we need, and much more; and, above all, we have the sweet, abiding sense of forgiveness, notwithstanding "our inventions." When we smart under chastisements or disappointments, we know that it is the fire which burns up the hay, wood, and stubble —a Father's dealings in compassion and mercy. We willingly, we gladly take these chastisements, which now are to us fresh pledges of our safety. For safe, eternally safe, remains the foundation, and unclosed the way of access. O surely with all our heart do we accord: "Exalt Jehovah our God, and worship at his holy hill; for Jehovah our God is holy." Alfred Ederaheim.
