Revelation 2:17,18,23
“He who has an ear, let him hear what the Spirit says to the churches. To him who overcomes I will give some of the hidden manna to eat. And I will give him a white stone, and on the stone a new name written which no one knows except him who receives it.” ’ “And to the messenger of the church in Thyatira write, ‘These things says the Son of God, who has eyes like a flame of fire, and His feet like fine brass:.... "all the churches shall know that I am He who searches the minds and hearts. And I will give to each one of you according to your works."
