Our reply to all these questions is at once simple and direct; and it is this: The very passages which we might least expect to find on the page of inspiration teach us, in their own peculiar way, the moral material of which we are made, and the moral depths into which we are capable of plunging. And is not this of great moment? Is it not well to have a faithful mirror held up before our eyes, in which we may see every moral trait, feature, and lineament perfectly reflected? Unquestionably. We hear a great deal about the dignity of human nature, and very many find it exceedingly hard to admit that they are really capable of committing some of the sins prohibited in the section before us, and in other portions of the divine volume; but we may rest assured that when God commands us not to commit this or that particular sin, we are verily capable of committing it. This is beyond all question. Divine wisdom would never erect a dam if there was not a current to be resisted. There would be no necessity to tell an angel not to steal; but man has theft in his nature, and hence the command applies to him. And just so in reference to every other prohibited thing; the prohibition proves the tendency--proves it beyond all question. We must either admit this or imply the positive blasphemy that God has spoken in vain. But then, it may be said, and is said by many, that while some very terrible samples of fallen humanity are capable of committing some of the abominable sins prohibited in Scripture, yet all are not so. This is a most thorough mistake. Hear what the Holy Ghost says in the seventeenth chapter of the prophet Jeremiah. "_The heart_ is deceitful above all things, and desperately wicked." Whose heart is he speaking of? Is it the heart of some atrocious criminal, or of some untutored savage? Nay; it is the human heart--the heart of the writer and of the reader of these lines. Hear also what our Lord Jesus Christ says on this subject.--"Out of _the heart_ proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies." Out of what heart? Is it the heart of some hideously depraved and abominable wretch, wholly unfit to appear in decent society? Nay; it is out of the human heart--the heart of the writer and of the reader of these lines. Let us never forget this; it is a wholesome truth for every one of us. We all need to bear in mind that if God were to withdraw His sustaining grace for one moment, there is no depth of iniquity into which we are not capable of plunging; indeed, we may add--and we do it with deep thankfulness--it is His own gracious hand that preserves us, each moment, from becoming a complete wreck in every way,--physically, mentally, morally, spiritually, and in our circumstances. May we keep this ever in the remembrance of the thoughts of our hearts, so that we may walk humbly and watchfully, and lean upon that arm which alone can sustain and preserve us.
