Deuteronomy 25, Psalm 116, Isaiah 52, Revelation 22

Revelation 22:16
As we began to read Revelation, I suggested the study of Jesus' names and descriptions through the book would be of great value in knowing Him.  In this verse, Jesus, Himself, provides the last name we are given in Revelation.  "I, Jesus, have sent my angel to testify to you about these things for the churches.  I am the root and the descendant of David, the bright morning star."
Jesus confirms in 22:16 what Revelation 1:1 tells us - He sent His angel to John so His church would know those things that must soon take place.  The last direct quote of Jesus in Scripture is to affirm everything in Revelation and to seal it with another of His "I am" statements.  The Gospel of John records seven times Jesus describes Himself as "I am":  the bread of life; the light of the world; the door of the sheep; the good shepherd; the resurrection and the life; the way, the truth and the life; and the true vine.  The NLT translates this verse as "I am both the source of David and the heir to his throne. I am the bright morning star."
Jesus' description of Himself as both the root and descendant of David fulfills the prophecy of Isaiah 11:1, "There shall come forth a shoot from the stump of Jesse, and a branch from his roots shall bear fruit."  He also answers His own question to the Pharisees in Matt 22:41-45.  How can the Messiah be both David's son and his Lord?
Each of Jesus' titles and names gives us a distinct quality or attribute of who He is.  I suspect some of the names of Jesus you have seen in reading Revelation stir you more than others.  The "bright morning star" is one of mine.
As I have said before, I love the early morning before the sun comes up.  That period of the day between Venus (the morning star) appearing in the eastern sky and the sun fully rising has proven to be my "quality time" with the LORD. 
Years ago when I was a roughneck (that is a low-level employee on a drilling rig) in West Texas, I diligently watched for the morning star.  Working from 6 pm until 6 am, a drilling crew was ready to go home but could not leave until another crew replaced them.  It was foolish to watch for the head lights of the relief's car until the morning star appeared.  But as soon as the star was visible, we all kept a sharp eye for the coming relief.
After I became a believer, that experience became a metaphor for my life in Christ.  2 Peter 1:19 speaking of Scripture says, "You would do well to pay attention as to a lamp shining in a dark place, until the day dawns and the morning star rises in your hearts."  I came to understand Jesus, the Morning Star, was my true relief, my true rest, my true redemption, my only salvation. 
Jesus, thank You for the many names and descriptions Your word provides.  It is our desire to know You as the One who holds the seven stars in his right hand, as the first and the last, as the one who has the two-edged sword, the Son of God, as Him who has the seven spirits of God, as the holy one, the true one, who has the key of David, as the Amen, the faithful and true witness, and the Bright Morning Star, who rises in our heart.
