On Joel 2:20

QUESTION: Explain this prophecy of Joel 2:20, "And I will show wonders in the heavens and in the earth: blood and fire and pillars of smoke. The sun shall be turned into darkness," etc.

ANSWER: The destruction of Jerusalem in A.D. 70 is here predicted, as explained by Christ in Matt. 24:29­ 44, and Luke 21:20-33. Peter also quotes this passage with its context and applies the whole in Acts 2:16­ 20 to the day of Pentecost and to the great changes of things in Palestine, which were soon to follow, and which did occur in about thirty-five years, while some of that generation were still living, as Jesus foretold. In answer to the objection that the language is too strong and too wide in the extent of the calamities predicted, which are seemingly universal, we beg the reader to read Joel 5:10, where the plague of locusts is thus vividly described, "the earth shall quake before them, the heavens shall tremble, the sun, and moon shall be dark; and the stars shall withdraw their shining." See also Amos 8:9, where the chastisement of Israel is thus portrayed, "I will cause the sun to go down at noon, and I will darken the earth in a clear day."
