Joseph Smith History

Conspiracy Rising Ref. 32

41 He also quoted the second chapter of Joel, from the twenty-eighth verse to the last. He also said that this was not yet fulfilled, but was soon to be. And he further stated that the fulness of the Gentiles was soon to come in. He quoted many other passages of scripture, and offered many explanations which cannot be mentioned here.

Joel 2
28 ¶And it shall come to pass afterward, that I will pour out my spirit upon all flesh; and your sons and your daughters shall prophesy, your old men shall dream dreams, your young men shall see visions:
29 And also upon the servants and upon the handmaids in those days will I pour out my spirit.
30 And I will shew wonders in the heavens and in the earth, blood, and fire, and pillars of smoke.
31 The sun shall be turned into darkness, and the moon into blood, before the great and the terrible day of the Lord come.
32 And it shall come to pass, that whosoever shall call on the name of the Lord shall be delivered: for in mount Zion and in Jerusalem shall be deliverance, as the Lord hath said, and in the remnant whom the Lord shall call.

The mention in the scriptures of things happening soon probably refers to how quickly they happen when they do happen. It is likely that the fulness of the Gentiles, which has been anticipated for nearly two hundred years, will happen quickly when it does happen.
