a glimpse of heaven

And after six days, Jesus took with him Peter and James and John his brother, and led them up a high mountain, by themselves. And he was transfigured before them, and his face shone like the sun, and his clothes became white as light....He was still speaking, when, behold, a bright cloud overshadowed them, and a voice from the cloud said, "this is my beloved Son, with whom I am well pleased; listen to him!" (Matthew 17:1-2, 5, ESV)
