[Signs mark, indicate, represent, symbolize, give direction, or point to other things beyond themselves, and are sometimes miraculous or extraordinary in nature. The scriptures speak of God's "signs and wonders" by which his work, power, and wisdom are made known or recognized by people in the earth (Ex. 7:3-5). True signs provide objective evidence that an event can reasonably be expected, such as the new star in the east being a sign of Christ's birth (Matt. 2:1, 2) or certain dark clouds heralding a storm (Matt. 16:1-4). False or counterfeit signs are deceptive and give a false hope of security if accepted (Ex. 7:11-12; 8:7; D&C 63:7-9.
