Now believe me, my friends, as surely as a man's flesh can die and be buried, while he himself, his soul, lives for ever, just so a man's self, his soul, can die, while his flesh lives on upon earth. You do not think so, but the Bible thinks so. The Bible talks of men being _dead_ in trespasses and sins, while their flesh and body is alive and walking this earth. It talks, too, of a worse state, of men twice dead; of men, who, after God has brought their souls to life, let those souls of theirs die down again within them, and rot away, as far as we can see, hopelessly and for ever. And what is it which kills a man's soul within him on this side the grave, and makes him dead while he has a name to live? _Sin_, evil-doing, the disease of the soul, the death of the soul, yea, the death of the man himself. And what is sin but living according to the flesh, and not according to the spirit? What is sin but living as the dumb animals do, as if we were debtors to our own flesh, to fulfil its lusts, and to please our own appetites, fancies, and tempers, instead of remembering that we are debtors to God, who made us, and blesses us all day long;--debtors to our Lord Jesus Christ, who bought us with His own blood, that we might please Him and obey Him;--debtors to God's Holy Spirit, who puts into our minds good desires;--debtors to our baptism vows, in which we were consecrated to God, that He, and not this flesh of ours, might be our Master for ever? This is sin; to give way to those selfish and evil tempers, against which I warned you in the beginning of my sermon, and which, if any man indulges in them, will surely and steadily, bit by bit, kill that man's soul within him, and leave the man dead in trespasses and sins, while his body walks this earth.
