Alma 12:16-18

16 And now behold, I say unto you then cometh a death, even a second death, which is a spiritual death; then is a time that whosoever dieth in his sins, as to a temporal death, shall also die a spiritual death; yea, he shall die as to things pertaining unto righteousness.

17 Then is the time when their torments shall be as a lake of fire and brimstone, whose flame ascendeth up forever and ever; and then is the time that they shall be chained down to an everlasting destruction, according to the power and captivity of Satan, he having subjected them according to his will.

18 Then, I say unto you, they shall be as though there had been no redemption made; for they cannot be redeemed according to God’s justice; and they cannot die, seeing there is no more corruption.

This is a long, powerful, comprehensive answer to Zeezrom's inquiry about the Resurrection.

The Spirit must have told Alma that he (and hopefully others in the crowd) were ready and willing to hear it.

How I WISH I could have witnessed this miraculous, almost instantaneous, conversion.
