Revelation 2:26-29

"To him who overcomes and does my will to the end, I will give authority over the nations--'He will rule them with an iron scepter; he will dash them to pieces like pottery'--just as I have received authority from my Father. I will also give him the morning star. He who has an ear, let him hear what the Spirit says to the churches."

To him who overcomes

and does my will to the end

He who has an ear, let him hear
