Now, when such sorrow is exercised toward God for wrong done to Him, when that wrong is deeply deplored, is honestly confessed, and is followed by a permanent reformation, that is repentance toward God. Such repentance God requires; nor can one become a Christian who does not exercise it. This is one unalterable condition of salvation. I do not mean that the penitent sinner will never afterwards, in no instance, sin again. He may sometimes, again, do wrong, for so long as he is in the world imperfection will pertain to him; but the ruling power of sin will be broken in his heart. He may sometimes sin; but whenever he does he will lament it. He will retire to his closet, and while there alone with God his tears will flow. Oh! how will he pray and wrestle that he may be forgiven; and what solemn resolutions will he make to sin no more! This he will continue to do month after month, and year after year, as long as he lives, as long as he ever does any wrong. To forsake sin becomes a principle of his life; to confess and forsake it, a habit of his soul. Repentance, then, is the first step.

But the Bible adds, "Repent and believe on the Lord Jesus Christ, and thou shalt be saved." Belief, or faith, as it is called, is another exercise required in order to be saved. What now is faith? Let me illustrate this.

Suppose a person is standing on the branch of a tree. It appears to be sufficiently firm to bear him, and he feels secure. But presently he perceives that it is beginning to break, and if it break he may be dashed on the rocks below. What shall he do? He looks abroad for help. At this critical moment a person presents himself at the foot of the tree, and says, "Let go, let go, and I will catch you." But he is afraid. He fears that the person may not be able, or may be unwilling to save him. But the branch continues to break, and destruction is before him. Meanwhile the kind-hearted person below renews his assurance, "Let go, let go, confide in me and I'll catch you." At last the person on the branch becomes satisfied that no other hope remains for him, so he says, "I'll do as this friend bids me; I'll trust him." He lets go, falls, and the other catches him. This is faith, or in other words it is confidence.

Now the sinner is liable to fall under the wrath of God for the wrong he has done, and there to perish. He may repent of that wrong, and repentance is most reasonable, and is, we have seen, required; but repentance of itself never repairs a wrong. One may repent that he has killed another, but that does not restore life. One may be sorry that he has broken God's commands, but that does not repair the dishonor done to the Divine government. That government must be upheld. How can it be done? I will tell you how it has been done. Christ consented to take the sinner's place. On the cross he suffered for and instead of the sinner; and God has decided that whosoever, being penitent for sin, will confide in his Son, or trust him, shall be saved.

Sinners are wont to put a high value upon some goodness which they fancy they possess, or upon good actions which they imagine they have done. These, they conceive, are sufficient to save them; and sinners generally feel quite secure. How little concerned, my son, have you been. But sinners mistake as to their goodness. They are all "dead in trespasses and sins." They are under condemnation. They are in imminent danger. Any day they may fall into the hands of an angry God. Sinners under conviction see this and feel this. The branch of self-righteousness on which they stand is insufficient to bear them. By-and-by it begins to give way. When the sinner feels this he cries, "What shall I do? Who will save me?"

Now Christ is commissioned to save, and when the poor sinner sees that he is about to perish, and in that state cries for help, Christ comes to him and says, "Let go all hope in yourself; let go dependence upon every other thing; trust to me and I will save you." "Come, for all things are ready." But may be the sinner is afraid. Will Christ do as he promises? Is he able to save? Well, the sinner looks round—he hesitates—perhaps prays—weeps—promises; but while all these are well enough in their places, they never of themselves bring peace and safety to the anxious heart. At length he sees and feels that there is no one but Christ, who stands as it were at the bottom of the tree, that can save him. And now he lifts up his voice and cries, "Lord, save me, or I perish." Into the hands of Christ he falls, and from that moment he is safe. This is Gospel faith or confidence.

And this repentance and faith which I have described are necessary in order to salvation. So the Bible decides; and whenever a soul exercises them that soul is a Christian soul, and that man is a Christian man.

There is yet one question further of great moment. You hope, perhaps, that you are a Christian—that you have truly repented, and do exercise true faith. You ask, How shall one decide?

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.
