Alma alludes to why God is sparing in showing signs to those who do not exercise faith in Him.
“…There are many that do say: If thou wilt show unto us a sign from heaven, then we shall know of a surety; then we shall believe. Now I ask, is this faith? Behold I say unto you, Nay; for if a man knoweth a thing he hath no cause to believe, for he knoweth it. And now, how much more cursed is he that knoweth the will of God and doeth it not, than he that only believeth, or only hath cause to believe, and falleth into transgression.” (Alma 32:17-19)
-How many have developed spiritual character to the point where they would do the will of God no matter the difficulty involved in doing so?
