   • It is not in the power of the sins of our infirmity, to unbrother us; when we look at the acts themselves, they are heinous; when at the persons, they are so much more faulty as more obliged; but when we look at the mercy of thee who hast called us, now, Who shall separate us?1808, Joseph Hall, Contemplations on the Old Testament: Books xix, xx and xxi, page 512
