What does the Bible say about being radiant?

When I had seen the splendour of the love light that flooded the world, I was beside myself with joy.

All the many loves, which I had known on your side faded into insignificance beside the great glowing radiance of that love, which swathed me about as with a garment and enabled me to see what marvellous possibilities, what undreamed-of powers were all the while in the heart of each of us. 

For there is no other word for it but love. 

God is Love, and Love is God, and the mystic power of God is Love.
