Thus understood, St. Paul's language becomes exceedingly suggestive of things that it is worth our while to forget, and the way in which we should forget them. Like him, we are not required to blot out the remembrance of the past. There could be no improvement if we did not remember past mistakes and profit by them. It is often our sweetest joy and highest pride to think of the days that are no more, of the wondrous history of mankind, of our own journey as Providence has led us on, and above all things, of him whom we are to hold in everlasting remembrance. But we must keep life's balance true. Some people are always living among the gravestones, regretting what is now inevitable, mourning over losses that cannot be repaired, thinking the days of old better than those which are to be--and wasting their energies in sorrowful reminiscences and wistful longings for a perished past, instead of using their energies in the accomplishment of what may be done for the winning of better crowns. It is against this practice that the apostle's experience warns. This practice makes progress impossible. It is a source of misery. It fetters the Christian mind. It does not know that the resurrection has taken place. It makes life a threnody instead of a hosanna. We are to turn from the past that we may obtain the better future. Let me give you an example of the way in which we are to forget the things which are behind, and reach forth unto those things that are before. I. It is worth our while to forget old doubts and questionings, through absorption in the practical application of the truth brought us by Jesus Christ. Most of the doubts and questionings which men have on the subject of religion are very old. Their hair is gray with the anxious thought of many centuries. They may be represented by old men, with wrinkled foreheads and feeble knees, pretending by dress and manner to be young. But you would be surprised to find how old they are, these questions that disturb your religious faith and hinder you from the performance of your whole duty. There, for instance, is that weary question about the reason why God allowed sin and misery to enter into his world--a question which men are still pondering, under which they are still restless and sometimes unhappy. But lo! it is as old as human history. The ancient Brahmins wrestled with it. We find it echoed in the hymns of Chaldea that date from the days of Abraham, in the songs of Greece, and in the literature of the age of Solomon; and neither philosophy nor science, neither discovery nor accident, has to this day been able to frame a satisfactory answer.
