“…and I will give him the morning star.”
In this verse, Jesus offers further benefits for those faithful in what they believe and how they live their lives.
and I will give him the morning star
Jesus gives a second promise to victorious Christians. He will give them “the morning star,” fellowship with the Lord Jesus Himself.
The “morning star” emerges just before dawn. The victor will not only share in the rights of a victor, but he will also enter into deep fellowship with Christ Himself when He comes again. Jesus gives conquering Christians unique wisdom about Himself. In eternity, our occupation and adoration will be the person of Christ. This fellowship with Him is ultimate well-being.
Principle:
Faithful Christians will share fellowship with the glory of King Jesus in His coming.
Application:
Jesus says He is the “bright and morning star” (Re 22:16). Jesus will come to get His own before He comes to receive His kingdom. This promise of His coming is the rapture of the church. Jesus will come for His own before He sets up His kingdom. Those who love Him look for that day with anticipation.

To only one person not all the Christians
King, this passage is the Lord speaking to a church of a number of members, not one as you claim.
