Charles H. Spurgeon on Psalms 11:7

That God may give grace without glory is intelligible; but to admit a man to communion with him in glory without grace, is not intelligible. It is not agreeable to God's holiness to make any inhabitant of heaven, and converse freely with him in a way of intimate love, without such a qualification of grace: "The righteous Lord loveth righteousness;" his countenance doth behold the upright;" he looks upon him with a smiling eye, and therefore he cannot favourably look upon an unrighteous person; so that this necessity is not founded only in the command of God that we should be renewed, but in the very nature of the thing, because God, in regard to his holiness, cannot converse with an impure creature. God must change his nature, or the sinner's nature must be changed. There can be no friendly communion between two of different natures without the change of one of them into the likeness of the other. Wolves and sheep, darkness and light, can never agree. God cannot love a sinner as a sinner, because he hates impurity by a necessity of nature as well as a choice of will. It is as impossible for him to love it as to cease to be holy. Stephen Charnock.
