The book of Joel prophesies this,6 as does the Apostle Peter in the book of Acts: “And it shall come to pass in the last days, saith GOD, I will pour out of MY SPIRIT upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams: And on MY servants and on MY handmaidens I will pour out in those days of MY SPIRIT; and they shall prophesy: And I will show wonders in heaven above, and signs in the earth beneath; blood, and fire, and vapour of smoke: The sun shall be turned into darkness, and the moon into blood, before that great and notable day of the LORD come: And it shall come to pass, that whosoever shall call on the name of the LORD shall be saved” (Acts 2:17-21).
Kitabu cha Yoeli kinatoa unabii huu,6 kama vile afanyavyo mtume Petro katika kitabu cha Matendo ya Mitume: “Itakuwa siku za mwisho, asema MUNGU, nitawamwagia watu wote ROHO YANGU na wana wenu na binti zenu watatabiri, na wana wenu wataona maono, na wazee wenu wataota ndoto: Naam, na siku zile nitawamwagia watumishi wangu wanaume na wanawake ROHO YANGU; nao watatabiri: Nami nitatoa ajabu katika mbingu juu, na ishara katika nchi chini; damu na moto, na mvuke wa moshi: Jua litageuka kuwa giza, na mwezi kuwa damu, kabla ya kuja kwa ile siku ya BWANA iliyo kuu na iliyo dhahiri: Na itakuwa, kila atakayeliitia jina la BWANA ataokolewa” (Matendo 2:17- 21).
