Note the evidence Moroni gave that bears witness to the miracles of God—the creation of heaven and earth (see Mormon 9:17), the creation of man (see verse 17), and the scriptural testimonies of the miracles of Jesus and the Apostles (see verse 18). The “God of miracles” described by Moroni can still be found. Elder Dallin H. Oaks bore witness that many miracles happen in our day and are present in the true Church of Jesus Christ:
“Many miracles happen every day in the work of our Church and the lives of our members. Many of you have witnessed miracles, perhaps more than you realize.
“A miracle has been defined as ‘a beneficial event brought about through divine power that mortals do not understand and of themselves cannot duplicate’ [in Daniel H. Ludlow, ed., Encyclopedia of Mormonism, 5 vols. (1992), 2:908]. The idea that events are brought about through divine power is rejected by most irreligious people and even by some who are religious. …
“… Miracles worked by the power of the priesthood are always present in the true Church of Jesus Christ. The Book of Mormon teaches that ‘God has provided a means that man, through faith, might work mighty miracles’ (Mosiah 8:18). The ‘means’ provided is priesthood power (see James 5:14–15; D&C 42:43–48), and that power works miracles through faith (see Ether 12:12; Moro. 7:37)” (“Miracles,” Ensign, June 2001, 6, 8).
Elder Bruce R. McConkie (1915–85) spoke of why miracles sometime cease:
“Why do signs and miracles cease in certain ages? Why are they not found at all times and among all peoples? Were those of old entitled to greater blessings than those of us who now dwell on the same earth that once was theirs? Moroni answers: ‘The reason why’ a God of gifts and miracles ‘ceaseth to do miracles among the children of men,’ and to pour out his gifts upon them, ‘is because that they dwindle in unbelief, and depart from the right way, and know not the God in whom they should trust.’ They worship false gods whom they define in their creeds, and they no longer walk in the same paths pursued by the saints of former days.
“It is men who have changed, not God; he is the same everlastingly. All men who have the same faith and live the same law will reap the same blessings” (A New Witness for the Articles of Faith [1985], 367).
