Charles H. Spurgeon on Psalms 78:11

And forgat his works, and his wonders that he had shewed them. Had they remembered them they would have been filled with gratitude and inspired with holy awe: but the memory of God's mercies to them was as soon effaced as if written upon water. Scarcely could one generation retain the sense of the divine presence in miraculous power, the succeeding race needed a renewal of the extraordinary manifestations, and even then was not satisfied without many displays thereof. Ere we condemn them, let us repent of our own wicked forgetfulness, and confess the many occasions upon which we also have been unmindful of past favours.
