I will tell you this also. Suppose you agree with a nurseryman to furnish you with a tree of a particular kind. He brings you one. You inquire, "Is this the kind of tree I engaged?" He replies, "Yes." But you say, "How do I know? It looks indeed like the tree in question, and you say it is; but there are other trees which strongly resemble it." He rejoins, "I myself grafted it, and I almost know." "Ah! yes, _almost_; but are you certain?" "No," he replies, "I am not absolutely certain, and no one can be sure at this moment." "But what shall I do?" you ask. "I want that particular tree." "Well," says he, "I will suggest one infallible test. Set it out on your grounds. It will soon bear _fruit_, and that will be a sure and satisfactory test." "Is there no other way?" you ask--"no shorter, better way?" "None," he replies. "This is the only sure evidence which man can have." Let us apply these remarks. As there is but one infallible test as to a tree, so there is but one in respect to a man claiming to be a Christian. "What _fruit_ does he bear?" "By their fruits," says our Savior, "ye shall know them." Only a good tree brings forth good fruit. Here, then, we have a plain, simple, and, I may add, infallible rule for testing ourselves. What kind of fruit are we bearing? What fruit must we bear? "The fruits of the Spirit," says the Bible, "are love, joy, peace, long-suffering, gentleness, goodness, faith," &c. If, then, we have been born of the Spirit, _i.e._, born again, or in other words, if we are Christians, we shall bear the fruits of the Spirit. I have known persons suggest various marks or tests by which to try themselves; but I have never found any which could certainly be depended upon besides the one which I have named--_the fruit which one brings forth_. The application of this test requires time. For evidence of Christian character, a person must examine himself month after month and year after year. His great aim must be to glorify God. He will, therefore, strive to keep his commandments. He will shun all known evil, and let others see that he sets a high value upon all that is "lovely and of good report." He will pray, not one day or one month, but habitually. His life will be a life of prayer, and in all the duties of the Christian profession he will endeavor to persevere. He will find himself imperfect, and will sometimes fail; but when he fails he will not sink down in despair and give up, but he will repent and say, "I'll do better next time;" and thus he will go forward gathering strength. Many trials and difficulties he will find, but the way will grow smoother and easier. His evidence will increase. The path of the righteous is as the light which shines brighter and brighter unto the perfect day.
