Who covereth thyself with light as a garment: Who stretchest out the heavens like a curtain: Who layeth the beams of his chambers in the waters: Who maketh the clouds his chariot: Who walketh upon the wings of the wind: Who maketh his angels spirits: his ministers a flaming fire: Who laid the foundations of the earth, that it should not be removed for ever.
For God who said, "Out of darkness let light shine," is He who has shone in our hearts to give us the light of the knowledge of God's glory, which is radiant on the face of Christ.
~2 Corinthians 4:6~
His Son is the radiance of his glory, the very image of his substance, and upholding all things by the word of his power, when he had by himself made purification for our sins, sat down on the right hand of the Majesty on high;
(a) Especially, emitting or darting rays of light or heat;
issuing in beams or rays; beaming with brightness; emitting a vivid light or splendor; as, the radiant sun.
