Luke 18:1
1-5. always—Compare Lu 18:7, "night and day."
faint—lose heart, or slacken. Romans 12:12
12. Rejoicing, &c.—Here it is more lively to retain the order and the verbs of the original: "In hope, rejoicing; in tribulation, enduring; in prayer, persevering." Each of these exercises helps the other. If our "hope" of glory is so assured that it is a rejoicing hope, we shall find the spirit of "endurance in tribulation" natural and easy; but since it is "prayer" which strengthens the faith that begets hope and lifts it up into an assured and joyful expectancy, and since our patience in tribulation is fed by this, it will be seen that all depends on our "perseverance in prayer."
1 Thessalonians 5:17
17. The Greek is, "Pray without intermission"; without allowing prayerless gaps to intervene between the times of prayer.
