Favorite Verse — The Son radiates God’s own glory and expresses the very character of God, and he sustains everything by the mighty power of his command. When he had cleansed us from our sins, he sat down in the place of honor at the right hand of the majestic God in heaven. This shows that the Son is far greater than the angels, just as the name God gave him is greater than their names. — Hebrews 1:3-4
