26 The one who is victorious and keeps My works to the end: I will give him authority over the nations
A professing Christian is victorious by living according to holy scripture and those with genuine faith will endure according to Philippians 1:6 which says, “6 I am sure of this, that He who started a good work in you will carry it on to completion until the day of Christ Jesus.”
The phrase “I will give him authority over the nations” could be talking about Jesus’ millennial reign which the saints are going to participate in His earthly kingdom. Their reward seems to involve authority.
27 and he will shepherd them with an iron scepter; he will shatter them like pottery— just as I have received this from My Father.
Shepherd refers to leadership and iron scepter means great power and authority which Jesus’ saints will have.
Jesus received all authority from the Father and can give authority to His saints to rule alongside Him in righteousness.
28 I will also give him the morning star.
Morning star in Revelation 22:16 refers to Jesus and in Isaiah 14:12 it refers to lucifer which is a Latin translation of morning star. In the context morning star refers to authority just like Lucifer had before his fall. Those who are victorious will shine like the morning star with the authority given by Jesus Christ.
29 “Anyone who has an ear should listen to what the Spirit says to the churches.
Again, the Lord is trying to let the readers know the importance in obeying the Word of God. When we read the Bible every day, we must pay close attention to what the Spirit of God is telling us through His Word.
