I tell you that he will avenge them speedily. Nevertheless when the Son of man comes, shall he find faith on the earth?

When the Son of man cometh. He comes to the universal judgment, when He will deliver His elect, whom He ordered to be always ready and eager; and to await that day patiently, preparing themselves for it by prayer and good works. For that day will be sudden and unexpected like lightning, as He Himself has said (chap. xvii24). Christ gives the reason why we should always pray, and persevere in prayer; because from His long absence, faith will fail even in many who believe, so that they will either lose all faith or believe very feebly, scarcely thinking that He will return at all.

(St. Augustine, de verb. Dom. Serm 36.)
