We know enough. Words of Mormon Chapter 1

4 And the things which are upon these plates ^apleasingme, because of the prophecies of the coming of Christ; and my fathers knowing that many of them have been fulfilled; yea, and I also know that as many things as have been^bprophesied concerning us down to this day have been fulfilled, and as many as go beyond this day must surely come to pass—

 7 And I do this for a ^awise ^bpurpose; for thus it whispereth me, according to the workings of the Spirit of the Lord which is in me. And now, I do not know all things; but the Lord ^cknoweth all things which are to come; wherefore, he^dworketh in me to do according to his ^ewill.

Book of Mormon: Words of Mormon Chapter 1: 4,7

     The Lord sent us here without knowledge of who we are or where we came from.  He did this so could practice faith and grow.  The Lord is wise and He knows everything, He knows we needed this in order to become like Him and experience wonderful joy.  
     But, He has provided Prophets and scripture.  We don't know all the answers, but we know enough.  We know enough in order to be prepared.  We are blessed with a Prophet just for our day.

Love,
