Charles H. Spurgeon on Psalms 90:8

God needs no other light to discern our sins by but the light of his own face. It pierceth through the darkest places; the brightness thereof enlightens all things, discovers all things. So that the sins that are committed in deepest darkness are all one to him as if they were done in the face of the sun. For they are done in his face, that shines more, and from which proceeds more light than from the face of the sun. So that this ought to make us the more fearful to offend; he sees us when we see not him, and the light of his countenance shines about us when we think ourselves hidden in darkness. Our sins are not only then in his sight when they are a committing and whilst the deed is doing; but ever after, when the act is past and gone and forgotten, yet then is it before the face of God, even as if it were in committing: and how should this make us afraid to sin! When our sins are not only in his sight while they are a committing, but so continue still for ever after they are past and done. God sets our sins before him; this shows he is so affected with them, he takes them so to heart, that he doth in a special manner continue the remembrance of them. As those that having had great wrong will store it up, or register it, or keep some remembrance of it or other, lest they should forget, when time shall serve, to be quit with those that have wronged them: so doth God, and his so doing is a sign that he takes our sins deeply to heart; which should teach us to fear the more how we offend him. When God in any judgment of death, or sickness, or loss of friends, shows his wrath, we should think and meditate of this; especially when he comes nearest us: Now the Lord looks upon my sins, they are now before him; and we should never rest till we have by repentance moved him to blot them out. Yea, to this end we should ourselves call them to remembrance. For the more we remember them, the more God forgets them; the more we forget them, the more God remembers them; the more we look upon them ourselves, the more he turneth his eyes from them. —William Bradshaw.
