We need to be straitly warned, that it is no light matter whether we repent or not. We need to be reminded, that there is a hell as well as a heaven, and an everlasting punishment for the wicked, as well as everlasting life for the godly. We are fearfully apt to forget this. We talk of the love and mercy of God, and we do not remember sufficiently His justness and holiness. Let us be very careful on this point. It is no real kindness to keep back the terrors of the Lord. It is good for us all to be taught that it is possible to be lost forever, and that all unconverted people are hanging over the brink of the pit.
