In his own words on Joel

• Joel 1:4

  For although the Lord has granted strong cattle, bodily health, a successful outcome to every activity and prosperous deeds, prayer must still be offered lest, as it is written, there be "a heaven of brass and an earth of iron" and lest "the swarming locust eat what the cutting locust has left, and the caterpillar devour what the swarming locust has left, and the blight consume what the caterpillar has left." Not in this alone does the effort of the toiling farmer stand in need of divine assistance. [His effort] must also fend off unexpected accidents by which, even if a field is loaded with the desired fruitful yield, he will not only be frustrated by waiting in vain for what he has hoped for but will even be deprived of the abundant crop that has already been harvested and that is stored on the threshing floor or in the barn.

  CONFERENCE 13:3.4

• Joel 3:10-11

  Whoever is protected by these weapons is always defended from the enemy's spears and devastation and will not be led as a captive and a slave, bound in the chains of the ravagers, to the territory of hostile thoughts. Nor will he hear through the prophet, "Why have you grown old in a foreign land?" But he will live triumphant and victorious in that region of thoughts where he wanted to be.Do you also want to understand the strength and fortitude of this centurion, by which he bears these weapons that we have spoken about and that are not carnal but powerful to God? Listen to the king himself and how he recruits the strong men that he gathers for his spiritual army, marking them and proving them: "Let the weak say," he says, "that I am strong." And, "The one who suffers shall be a fighter." You see, then, that the Lord's battles can be fought only by the suffering and the weak. Indeed, certainly fixed in this weakness, our gospel centurion said with confidence, "When I am weak, then I am strong." And again, "Strength is perfected in weakness." One of the prophets says about this weakness, "The one who is weak is among them shall be as the house of David." The patient sufferer shall also fight these battles with that patience of which it is said, "Patience is necessary for you so that you may do the will of God and receive a reward."
