In this sermon Things That Cannot Be Shaken, we learn if a Person’s beliefs is a preference  or  a conviction. It is perfectly known and established, whereas all earthly things are liable to fluctuation and revolution. Preference is a very strong belief you hold with great intensity and strength. You would go into full-time service due to a strong preference of your belief, and put all of your wealth into this.  Become a minister, a passer, go out on every visitation. You would proselytize others into believing this. You would teach this to your children, and have tremendous belief and zeal for this belief;  BUT, under some circumstances you would change this belief.
