2 Corinthians 6:5 In stripes, in imprisonments, in tumults, in labours, in watchings, in fastings;

“Watchings” literally means “sleeplessness”, that is, a keeping awake, having to maintain sleepless nights. It is a physical, mental challenge to keep awake when the body and mind are exhausted. William MacDonald observed well, “Sleeplessness describes his constant need for being on the alert against the wiles of the devil and the efforts of his enemies to harm him.” In the thick of mission work, he encountered much resistance. As such, he has to persist in prayer and on the lookout for the slightest sign of danger.
