Light doesn't come from some personal power, idea, or skill - light comes from reflection. I am a moon. This light is not produced, it is received (Romans 7:18, Romans 8:11, John 1:4). Those who meet the LORD face to face, it is they who reflect the light of God and shine with His light. I want this to be true of me, too!
"The LORD make His face shine on you..." -Numbers 6:25
"Blessed are the people who know the joyful sound!
They walk, O LORD, in the light of Your countenance." -Psalm 89:15
For your light has come!
And the glory of the LORD is risen upon you." -Isaiah 60:1

Out of Zion, the perfection of beauty,
God will shine forth.
