Prayer

Probably anyone who’s been Christian long enough to have listened to more than a few sermons has heard, time after time, that we should pray at all times. This is partly a generalisation of how every major Biblical figure seems to pray before and after doing just about anything of importance, as well as many specific instructions to pray frequently, but it’s stated most directly by St. Paul at 1 Thess. 5:17, “Never cease praying,” and by Christ Himself at Luke 21:36, “Keep watch, then, praying at all times, so that you may be found worthy to come safe through all that lies before you, and stand erect to meet the presence of the Son of Man.” When quoted directly, preachers typically qualify it as not literal, but nonetheless, how does one go about praying at all times?
