Charles H. Spurgeon on Psalms 89:15

They shall walk in the light of thy countenance. Surely, next to the love of God's heart, believers value the smiles of his face; from which, as from the agency of the sun, arise the budding of conscious joy, the leaves of unsullied profession, the variegated blossom of holy tempers, and the beneficent fruits of moral righteousness. They are totally mistaken who suppose that the light of God's countenance, and the privileges of the gospel, and the comforts of the Spirit, conduce to make us indolent and inactive in the way of duty. The text cuts up this surmise by the roots. For, it does not say, they shall sit down in the light of thy countenance; or, they shall lie down in the light of thy countenance; but "they shall WALK in the light of thy countenance." What is walking? It is a progressive motion from one point of space to another. And what is that holy walking which God's Spirit enables all his people to observe? It is a continued, progressive motion from sin to holiness; from all that is evil, to every good word and work. And the self same "light of God's countenance" in which you, O believer, are enabled to walk, and which at first gave you spiritual feet wherewith to walk, will keep you in a walking and in a working state, to the end of your warfare. —Augustus Montague Toplady.
