This is what is sometimes denominated walking in a "general and indistinct faith;" or walking in the "obscurity of faith," or in the "night of faith." Faith, in its relation to the subject of it, is truly a light in the soul; but it is a light which shines only upon duties, and not upon results or events. It tells us what is now to be done, but it does not tell us what is to follow. And accordingly it guides us but a single step at a time. And when we take that step, under the guidance of faith, we advance directly into a land of surrounding shadows and darkness. Like the patriarch Abraham, we go, not knowing whither we go, but only that God is with us.
Blessed and glorious way of living! Indeed, it is the only life worth possessing; the only true life. "Let the heathen rage, and the people imagine a vain thing;" let nations rise and fall; let the disturbed and tottering earth stand or perish; let God reveal to us the secret designs of his providence or not, it is all well. "Cast all your cares upon God, for he careth for you." Our heavenly Father is at the helm. The winds blow, the waves swell, the clouds gather around, but we sail in a strong vessel. There is no port at hand, and there is no sun or star to guide us. Faith, therefore, in the defect of all things else, must constitute our port and our anchor, our sun and our favoring breeze; but we have all that we can ask, in having perfect confidence in our great Commander. It is the blessed privilege of faith, even in our darkest and most disastrous moments, to assure us that we are safe, forever safe, in the mighty keeping of God's holy will.
