Apostasy is to precede the second coming!
(2 Thessalonians 2:3) Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
We have been commanded to study the words of Isaiah, and he has a lot to say about end time apostasy.
(3 Ne 23-14) 1 And now, behold, I say unto you, that ye ought to search these things. Yea, a commandment I give unto you that ye search these things diligently; for great are the words of Isaiah.
2 For surely he spake as touching all things concerning my people which are of the house of Israel; therefore it must needs be that he must speak also to the Gentiles.
3 And all things that he spake have been and shall be, even according to the words which he spake. (Isaiah uses the past to tell us what will happen in the future)
4 Therefore give heed to my words; write the things which I have told you; and according to the time and the will of the Father they shall go forth unto the Gentiles.
