Charles H. Spurgeon on Psalms 105:8

He hath remembered his covenant. As a long series of years had elapsed between the promise and the performance, the prophet uses the word "remember, "intimating that the Divine promise does not become obsolete by length of time, but that even when the world imagines that they are extinguished and wholly forgotten, God retains as distinct a remembrance of them as ever, that he may accomplish them in due season. John Calvin.
