They are not common among those who are called true Christians

I recently read a sermon by J. C. Ryle, "Remember Lot!" In it, Ryle looks at Gen 19:16 where it says, "He lingered" (referring to Lot), explaining who lot was (a Christian), why he lingered, and what happened because of it. Note this portion below. It seems times haven't changed much and this same text could have been written today:

You live in days when a lingering, Lot-like religion abounds. The stream of profession is far broader than it once was, but far less deep in many places. A certain kind of Christianity is almost fashionable now. To belong to some party in the Church of England, and show a zeal for its interests,—to talk about the leading controversies of the day,—to buy popular religious books as fast as they come out, and lay them on your table,—to attend meetings,—subscribe to societies,—and discuss the merits of preachers,—all these are now comparatively easy and common attainments. They no longer make a person singular. They require little or no sacrifice. They entail no cross.

But to walk closely with God, to be really spiritually-minded,—to behave like strangers and pilgrims,—to be distinct from the world in employment of time, in conversation, in amusements, in dress,—to bear a faithful witness for Christ in all places,—to leave a savour of our Master in every society, to be prayerful, humble, unselfish, meek,—to be jealously afraid of sin, and tremblingly alive to our danger from the world,—these, these are still rare things. They are not common among those who are called true Christians, and, worst of all, the absence of them is not felt and bewailed as it should be.

Elsewhere in the sermon he says:

...eminent holiness, and eminent usefulness, are most closely connected,—that happiness and following the Lord fully go side by side,—and that if believers will linger, they must not expect to be useful in their day and generation, or to enjoy great comfort and peace in believing.
