Did I not speak peace to your mind ?

“

The feeling of peace is the most common confirming witness that I personally experience. When I have been very concerned about an important matter, struggling to resolve it without success, I continued those efforts in faith. Later, an all-pervading peace has come, settling my concerns, as He has promised” (“Using the Supernal Gift of Prayer,” Ensign or Liahona, May 2007, Richard G. Scott)
