The Bible says that no one has ever seen the LORD who dwells in unapproachable light (1 Timothy 6:16). By this, we were without knowledge of what the sovereign, immortal God whom we worship was like. We guessed His character and pondered what form He should take. The men of old knew Him as fire, smoke, wind, and other elements that were only earthly and limited by our parochial minds.
However, everything changed when the supreme divinity, Jesus, stepped foot upon the earth and lived in our neighborhood. Then we began to see wisdom, kindness, compassion, love, and sweet attributes we had formerly second-guessed God to possess. We began to receive first-hand knowledge of what God looked like. We experienced His thought process and understood better what Yahweh had been from everlasting.
The glory of God is not simply the bright light that radiates in and around Him. It is the totality of Him. Since Jesus is the radiance of the glory of God and the exact imprint of his nature (Hebrews 1:3), then His manifestation is everything God is. And we learn from the Scriptures how He went about doing good (Acts 10:38). This is the character of God. It is God’s glory as revealed through Jesus.

Dear Heavenly Father, I thank You for Your glory clearly expressed in the life of Jesus on earth. Now, I see and know You. Now, I behold the full measure of Your glory. You have removed every veil and distance for me so that I can know and experience You. I want to see You and become more like You every day, Lord. Please help me keep my gaze on the beauty of Your Majesty. With You is life and everything noble and worthy of imitation. Help me walk like You, talk like You, and live like You. 
In Jesus's name I pray. Amen.
