The reference of these words is to Abram's act of faith in leaving Haran and setting out on his pilgrimage. It is a strange narrative of a journey, which omits the journey altogether, with its weary marches, privations, and perils, and notes but its beginning and its end. Are not these the main points in every life, its direction and its attainment? There are-- 'Two points in the adventure of the diver, One--when, a beggar, he prepares to plunge, One--when, a prince, he rises with his pearl.' Abram and his company had a clear aim. But does not the Epistle to the Hebrews magnify him precisely because he 'went out, not knowing whither he went'? Both statements are true, for Abram had the same combination of knowledge and ignorance as we all have. He knew that he was to go to a land that he should afterwards inherit, and he knew that, in the first place, Canaan was to be his 'objective point,' but he did not know, till long after he had crossed the Euphrates and pitched his tent by Bethel, that it was the land. The ultimate goal was clear, and the first step towards it was plain, but how that first step was related to the goal was not plain, and all the steps between were unknown. He went forth with sealed orders, to go to a certain place, where he would have further instructions. He knew that he was to go to Canaan, and beyond that point all was dark, except for the sparkle of the great hope that gleamed on the horizon in front, as a sunlit summit rises above a sea of mist between it and the traveller. Like such a traveller, Abram could not accurately tell how far off the shining peak was, nor where, in the intervening gorges full of mist, the path lay; but he plunged into the darkness with a good heart, because he had caught a glimpse of his journey's end. So with us. We may have clear before us the ultimate aim and goal of our lives, and also the step which we have to take now, in pressing towards it, while between these two there stretches a valley full of mist, the breadth of which may be measured by years or by hours, for all that we know, and the rough places and green pastures of which are equally hidden from us. We have to be sure that the mountain peak far ahead, with the sunshine bathing it, is not delusive cloud but solid reality, and we have to make sure that God has bid us step out on the yard of path which we _can_ see, and, having secured these two certainties, we are to cast ourselves into the obscurity before us, and to bear in our hearts the vision of the end, to cheer us amid the difficulties of the road.
