Signs do not produce faith. (D&C 63: 9.) Signs follow faith. (Id.)

Those who “seek signs” are wicked, often adulterous. (Matt. 12: 39, Matt. 16: 4.) Those who want a sign before they will believe cannot develop faith. (Ether 12: 6.)

Signs which follow faith do not come as a result of what men seek, but come as a result of what God wills. (D&C 63: 10.)

Signs, given by God, according to His will, create mighty works by men. (D&C 63: 11.) However, God’s mighty works are often accomplished by small means. Events that are “mighty even unto the power of deliverance” (1 Ne. 1: 20), can be accomplished by so little a means as God warning a family to flee. (1 Ne. 2: 2.)

God preserved His Son through “small means.” (Matt. 2: 13-14.)

The Lord preserved mankind through the destruction at the time of Noah using only a small family. (Gen. 7: 23.)

There will be “signs” and “small means” and “mighty works” still, but they will seem as nothing to those who do not believe. But to people of faith, they will be the power of God unto salvation.
