Charles H. Spurgeon on Psalms 143:1

Answer me in thy righteousness. Forgiveness is not inconsistent with truth or righteousness, and the pardon which in mercy God bestows upon the sinner is bestowed in justice to the well beloved Son who accepted and discharged the sinner's obligations. This is an infinitely precious truth, and the hearts of thousands in every age have been sustained and gladdened by it. A good old Christian woman in humble life so fully realized this, that when a revered servant of God asked her, as she lay on her dying pillow, the ground of her hope for eternity, she replied, with great composure, "I rely on the justice of God"; adding, however, when the reply excited surprise, "justice, not to me, but to my Substitute, in whom I trust." —Robert Macdonald, in "From Day to Day; or, Helpful Words for Christian Life," 1879.
