There is a generation of Christians in this age who grieve me to the heart. They make my blood run cold. I cannot understand them. For anything that man’s eye can see, they make no progress. They never seem to get on. Years roll on, and they are just the same — the same besetting sins, the same infirmities of disposition, the same weakness in trial, the same chilliness of heart, the same apathy, the same faint resemblance to Christ; but no new knowledge, no increased interest in the kingdom, no freshness, no new strength, no new fruits, as if they grew. Are they not forgetting that growth is the proof of life — that even the tree grows, and the snail and the sloth move? Are they not forgetting how awfully far a man may go, and yet not be a true Christian? He may be like a wax figure, the very image of a believer, and yet not have within him the breath of God — he may have a name to live, and be dead after all.

Brethren, these are the reasons why I write so strongly. I want your Christianity to be unmistakable. I want you all to grow really, and to do more than others. Let us all henceforth remember Sardis and Laodicea — let us resolve to be more holy and more bright. Let us bury our idols. Let us put away all strange gods. Let us cast out the old leaven. Let us lay aside every weight and besetting sin. Let us cleanse ourselves from all filthiness of flesh and spirit, and perfect holiness in the fear of God. Let us renew our covenant with our beloved Lord. Let us aim at the highest and best things. Let us resolve by God’s blessing to be more holy, and then I know and am persuaded we shall be more useful and more happy.
