"My beloved brothers and sisters, I testify of angels, both the heavenly and the mortal kind. In doing so I am testifying that God never leaves us alone, never leaves us unaided in the challenges that we face. '[N]or will he, so long as time shall last, or the earth shall stand, or there shall be one man [or woman or child] upon the face thereof to be saved.' On occasions, global or personal, we may feel we are distanced from God, shut out from heaven, lost, alone in dark and dreary places. Often enough that distress can be of our own making, but even then the Father of us all is watching and assisting. And always there are those angels who come and go all around us, seen and unseen, known and unknown, mortal and immortal."
