Answer:
. . . who alone has immortality, dwelling in unapproachable light, whom no man has seen or can see, to whom be honor and everlasting power. Amen (1 TIMOTHY 6:16).
EZEKIEL 1, ROMANS 3:23, JOHN 3:16, 4:24, 2 CORINTHIANS 4:6
How wonderful it will be to finally see God in all His glory. We read that God lives in light so bright that we could never come near it, and that He is a spirit. When the prophet Ezekiel described his vision of God, he included bright fire, flashes of lightning, even the brightness of a rainbow in a cloud on a rainy day. But we are all sinners and the Bible says because of this, we are blind to spiritual things. We are born sinners because of Adam’s disobedience in the Garden of Eden. And we can’t see God because of our sinfulness. So while we are here on earth, we cannot see Him; we cannot know what He looks like, even though He is present with us. However, we see the glory of God in the face of Jesus Christ as revealed in the Bible.
Now there is good news. God loved us and He had a plan that would save us. Jesus Christ stepped into history as a man, died on a cross, and rose from the dead. He promises that everyone who believes in Him, who calls on His name, who is sorry for his or her sins, and receives His free gift of forgiveness and salvation, will one day be with Him in heaven—where we will finally see our holy, merciful God.
