John Wesley on Hebrews 8:5

Who serve - The temple, which was not yet destroyed. After the pattern and shadow of heavenly things - Of spiritual, evangelical worship, and of everlasting glory. The pattern - Somewhat like the strokes pencilled out upon a piece of fine linen, which exhibit the figures of leaves and flowers, but have not yet received their splendid colours and curious shades. And shadow - Or shadowy representation, which gives you some dim and imperfect idea of the body, but not the fine features, not the distinguishing air; none of those living graces which adorn the real person. Yet both the pattern and shadow lead our minds to something nobler than themselves: the pattern, to that holiness and glory which complete it; the shadow, to that which occasions it. Ex 25:40.
