A careless admission that men are sinners is often made by persons who give themselves little concern about religion; and even acrimonious complaints may be freely vented by them against the iniquities of others. But such is the stupefying effect of human depravity, that men have very little complaint to make against themselves; and their condition, as sinners against God, awakens very little uneasiness. Occasionally conscience may be aroused, and produce alarm; but, through the deceitfulness of sin, its rebukes and warnings become unheeded, and men are again lulled to sleep in carnal security. Until this fatal slumber is broken, and a thorough, deep-rooted conviction of sin seizes the mind, and allows the man no quiet, his spiritual state exhibits no favorable indications.
Conviction of sin has sometimes produced very disquieting effects in the minds of heathen men, destitute of the true knowledge of God. Costly sacrifices and painful austerities have been resorted to for the purpose of appeasing their offended deities. Nature teaches men their danger, but cannot show them the way of escape. In these circumstances, how welcome is the light which the Bible throws on our path! It gives a far clearer discovery of our danger, and, at the same time, opens before us the door of hope.
Conviction of sin may at first respect merely our overt acts of wickedness; but, if thorough and effectual, it will extend to the depraved heart, from which evil actions proceed. It will open to our view this fountain of corruption, this deep sea casting up mire and dirt. To explore the deep windings of depravity, dark and filthy, we need the torch of revelation. Its use in making us acquainted with ourselves, demonstrates the divinity of its origin. The woman of Samaria said of Jesus, "Come see a man which told me all things that ever I did; is not this the Christ?" And the Bible, which tells us so exactly all that is in our hearts, must be from God, the Searcher of hearts. The world of iniquity within us was formerly to us a land unknown; but we have now explored it in part, and we can testify that the only correct map of it is in the Holy Scriptures. As we make progress in the knowledge of ourselves, throughout our course of religious experience, what we read in our own hearts and what we read in the Bible agree perfectly, and we ever carry with us a proof that the doctrine of the Bible is the truth of God.
Many who profess to regard the Bible as a revelation from heaven, do not receive its doctrine concerning the present state of man. They cannot conceive the human heart to be so deceitful and desperately wicked as the Bible declares it to be; and especially they do not so conceive of their own hearts. We hence know that such men could not have written the Bible. When the light of truth has produced in us a thorough conviction of sin, we read the Bible with new eyes, and we discover in it the handwriting of him who said, "I the Lord search the heart."
The exceeding sinfulness of sin appears when it is viewed as committed against God. David said, "Against thee, thee only, have I sinned." While under genuine conviction of sin, a view of God's perfections renders the conviction overwhelming. To have sinned against so glorious and excellent a being; to have rebelled against the rightful Sovereign of the universe, and aimed at dethroning him; to have violated his law, holy, just, and good; to have trampled his authority under our feet, insulted his majesty, despised the riches of his forbearance and goodness; to have persevered in our course, notwithstanding the calls of his mercy; and, in spite of all his warnings and threatening, to have, feeble worms as we are, defied his omnipotent vengeance; when such views of sin are presented, in the light of God's word, our souls are filled with anguish, and in the depth of sorrow and self-condemnation we adopt the publican's prayer, "God be merciful to me a sinner."
The word of God, which pierces to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart, often gives pain by its probing, but their tendency is salutary. They are unwelcome to hypocrites and false professors; but the man of sincere piety prays, "Search me, O God, and know my heart; try me, and know my thoughts; and see if there be any wicked way in me, and lead me into the way everlasting." The Bible tears the mask from the hypocrite, and shows to the Pharisee that all his righteousnesses are but filthy rags; but, humiliating as these wholesome instructions are, the true penitent rejoices to receive them. He fears to be deceived; and he blesses God for the light of truth, by which his true character is revealed.
When men's eyes are opened to see their spiritual danger, they generally attempt, in their own strength, to work out their salvation. These efforts prove unavailing; and they learn, by experience, that they have no help in themselves. This truth, though clearly taught in the Bible, they never really believed until it was thus learned. Here arises, in the heart of Christian experience, another confirmation of Bible doctrine. A truth which no man sincerely believes until the Spirit of God has taught him, by inward experience, must have proceeded from God. In the whole progress of our spiritual life we become increasingly convinced of our utter helplessness and entire dependence on strength divine; and the Bible doctrine on this subject acquires perpetually increasing confirmation.
Genuine Christian experience commences with conviction of sin; but, blessed be God, it does not end here. The knowledge of our depravity, condemnation, and helplessness, would fill us with despair, were it not that salvation, precisely adapted to our necessities, has been provided by the mercy of God, and revealed in the gospel of his Son. The very truth, which would otherwise fill us with anguish and despair, prepares for the joyful acceptance of salvation by Christ. He who rejects this truth does not feel the need of Christ; and, therefore, does not come to him for life. They that be whole need not a physician. Let the truth of this chapter be received deep in the heart, and we shall be prepared for the profitable study of the next subject.
