i always get confused when people say that they can do stuff after this life. marriage being the case here; baptism, repentance and sealings being examples of other conversations. i get confused because the book of mormon teaches that we have to use this life to prepare for the next. alma 34:33 says:
"...I beseech of you that ye do not procrastinate the day of your repentance until the end; for after this day of life, which is given us to prepare for eternity, behold, if we do not improve our time while in this life, then cometh the night of darkness wherein there can be no labor performed."
also, isn't the new and everlasting covenant of marriage polygamy? doesn't d and c 132 teach that?
