…let us lay aside every weight, and the sin which doth so easily beset us, and let us run with patience the race that is set before us… – Hebrews 12:1

A bad start is a sad thing. If, in the ancient races of Greece or Rome, a man who was about to run the race had loitered, or if he had started before the time it would not matter how fast he ran, if he did not start in order. The flag must drop before the horse starts; otherwise, even if it reach the winning post first, it shall have no reward. There is something to be noted, then, in the starting of the race. I have known men run the race of religion with all their might, and yet they have lost it because they did not start right. You say, “Well, how is that?” Why, there are some people who on a sudden leap into religion. They get it quickly, and they keep it for a time. and at last they lose it because they did not get their religion the right way. They have heard that before a man can be saved, it is necessary that, by the teaching of the Holy Spirit, he should feel the weight of sin, that he should make a confession of it, that he should renounce all hope in his own works, and should look to Jesus Christ alone. They look upon all these things as unpleasant preliminaries and therefore, before they have attended to repentance, before the Holy Spirit has wrought a good work in them, before they have been brought to give up everything and trust to Christ, they make a profession of religion.

How many there are who never think it necessary that there should be heart work within! Let us remember, however, that there never was a true new birth without much spiritual suffering;  that there never was a man who had a changed heart without his first having a miserable heart. We must pass through that black tunnel of conviction before we can come out upon the high embankment of holy joy; we must first go through the Slough of Despond before we can run along the walls of Salvation. ~ C.H. Spurgeon
