If life has a clear, definite aim, and especially if its aim is the highest, there will be detachment from, and abandonment of, many lower ones. Nothing worth doing is done, and nothing worth being is realised in ourselves, except on condition of resolutely ignoring much that attracts. 'They went forth'; Haran must be given up if Canaan is to be reached. Artists are content to pay the price for mastery in their art, students think it no hardship to remain ignorant of much in order to know their own subject thoroughly; men of business feel it no sacrifice to give up culture, leisure, and sometimes still higher things, such as love and purity, to win wealth. And we shall not be Christians after Christ's heart unless we practise similar restrictions. The stream that is to flow with impetus sufficient to scour its bed clear of obstructions must not be allowed to meander in side branches, but be banked up in one channel. Sometimes there must be actual surrender and outward withdrawal from lower aims which, by our weakness, have become rival aims; always there must be subordination and detachment in heart and mind. The compass in an iron ship is disturbed by the iron, unless it has been adjusted; the golden apples arrest the runner, and there are clogs and weights in every life, which have to be laid aside if the race is to be won. The old pilgrim fashion is still the only way. We must do as Abram did: leave Haran and its idols behind us, and go forth, ready to dwell, if need be, in deserts, and as sojourners even when among cities, or we shall not reach the 'land that is very far off.' It is near us if we forsake self and the 'things seen and temporal,' but it recedes when we turn our hearts to these.
