'Our line!' Astronomers take a thin thread from a spider's web and stretch it across their object glasses to measure stellar magnitudes. Just as is the spider's line in comparison with the whole shining surface of the sun across which it is stretched, so is what we have already attained to the boundless might and glory of that to which we may come. Nothing short of the full measure of the likeness of Jesus Christ is the measure of our possibilities. There is a mannerism in Christian life, as there is in everything else, which is to be avoided if we would grow into perfection. There was a great artist in the last century who never could paint a picture without sticking a brown tree in the foreground. We have all got our 'brown trees,' which we think we can do well, and these limit our ambition to secure other gifts which God is ready to bestow upon us. So 'forget the things that are behind.' Cultivate a wise obliviousness of past sorrows, past joys, past failures, past gifts, past achievements, in so far as these might limit the audacity of our hopes and the energy of our efforts. IV. So, lastly, pursue the aim with a wise, eager reaching forward. The Apostle employs a very graphic word here, which is only very partially expressed by that 'reaching forth.' It contains a condensed picture which it is scarcely possible to put into any one expression. 'Reaching out over' is the full though clumsy rendering of the word, and it gives us the picture of the runner with his whole body thrown forward, his hand extended, and his eye reaching even further than his hand, in eager anticipation of the mark and the prize. So we are to live, with continual reaching out of confidence, clear recognition, and eager desire to make our own the unattained. What is that which gives an element of nobleness to the lives of great idealists, whether they be poets, artists, students, thinkers, or what not? Only this, that they see the unattained burning ever so clearly before them that all the attained seems as nothing in their eyes. And so life is saved from commonplace, is happily stung into fresh effort, is redeemed from flagging, monotony, and weariness. The measure of our attainments may be fairly estimated by the extent to which the unattained is clear in our sight. A man down in the valley sees the nearer shoulder of the hill, and he thinks it the top. The man up on the shoulder sees all the heights that lie beyond rising above him. Endeavour is better than success. It is more to see the Alpine heights unscaled than it is to have risen so far as we have done. They who thus have a boundless future before them have an endless source of inspiration, of energy, of buoyancy granted to them.
