“Glory” is a light-filled word spilling out the extravagant brightness that marks      God's presence among us. It is also used to ascribe honor and dignity and “weightiness” to mountains and weather and men and women, but the most  prominent use in our Scriptures is in relation to God.
“No one has ever seen God” (John 1:18), but we do see his glory, the bright   splendor that marks God's presence, present among us here and now: at Sinai,
in the tabernacle, in the temple, and, most of all and most personally, in Jesus.1
