At the end of the day, that's the only theological question we ever debate. Oh, the issues and topics vary depending upon the day, from atonement theories to sexual ethics. But behind these topical debates there's always two rival visions of God being debated. We only really debate this same question over and over again.
So, what is God like?
Hebrews 1:3 has the answer:
The Son is the radiance of God’s glory and the exact representation of his being.Other translations render it as:
He is the radiance of the glory of God and the exact imprint of his nature.What is God like?
He reflects the brightness of God's glory and is the exact likeness of God's own being.
The Son shows the glory of God. He is a perfect copy of God’s nature.
God is like Jesus.
