Dr. Thomas Goodwin says somewhere that the worm that dieth not only comes to its sharpest sting and to its deadliest venom when it is hatched up under gospel light. The very light of nature itself greatly aggravates some of our sins. The light of our early education greatly aggravates others of our sins. But nothing wounds our conscience and then exasperates the wound like a past experience of the same sin, and, especially, an experience of the grace of God in forgiving that sin. Had we found young Presumption in his irons before his conversion, we would have been afraid enough at the sight. Had we found him laid by the heels after his first uncleanness, it would have made us shudder for ourselves. But we are horrified and speechless as we see him apprehended and laid in irons on the very night of his first communion, and with the wine scarcely dry on his unclean lips. Augustine postponed his baptism till he should have his fill of sin, and till he should no longer return to sin like a dog to his vomit. Now, next Sabbath is our communion day in this congregation. Let us therefore this week examine ourselves. And if we must sin as long as we are in this world, let it henceforth be the sin of ignorance and of infirmity.
So the three reprobates lay down to sleep again, and Christian as he left that bottom went on in the narrow way singing:
'O to grace how great a debtor Daily I'm constrained to be Let that grace, Lord, like a fetter, Bind my wandering heart to Thee.'
