I should try to do this, first, _by believing the weightiest doctrines_. I would believe not this "ism," nor that, but the unadulterated truth which Jesus taught; for a holy character will only grow by the Spirit of God out of true doctrine. Falsehood breeds sin: truth begets and fosters holiness. You and I therefore ought to select our seed carefully, and cast out all error. If we are wise we shall think most of the most important truths, for I have known people attach the greatest importance to the smallest things. They fight over the fitches, and leave the wheat to the crows. As for me, those who will may dispute over vials and trumpets, I shall mainly preach the doctrine of the precious blood and the glorious truths of substitution and atonement. These doctrines are the principal wheat, and therefore these shall have my choice. Next to that, we ought to sow _the noblest examples_. Many men are dwarfed because they choose a bad model to start with. They imitate dear old Mr. So-and-so till they grow wonderfully like him with the best of him left out. A minister happens to be of a gloomy turn of mind, and he preaches the deep experience of the children of God, and in consequence a band of good people think it their duty to be melancholy. Why need they fall into a ditch because their leader has splashed himself? We should never copy any man's infirmities. To be like Paul there is no need to have weak eyes; to be like Thomas there is no necessity to doubt. If you copy any good man, there is a point at which you ought to stop short. If I must have a human model, I would prefer one of the bravest of the saints of God; but oh how much better to follow that perfect pattern which you have in Christ Jesus! We should sow the best wheat by seeing that we have _the purest spirit_. Alas! how soon do spirits become soiled by self or pride, or despondency or sloth, or some earthly taint. But what a grand thing it is to live in the spirit of Christ! May we be humble, lowly, bold, self-sacrificing, pure, chaste, and holy.
