Basic Truth 13 · The Redeemer

Why must the Redeemer be truly God?

Because Jesus is God, he is infinite and holy — able to pay the penalty for an unlimited number of sins, and to bear a punishment no finite creature could survive.

“For in him the whole fullness of deity dwells bodily,”

Colossians 2:9 (ESV)

Paul isn’t describing Jesus as God-like, or carrying a portion of divine authority — he’s saying the entire fullness of deity lives in him, in an actual body. This is about as direct a statement of Christ’s full divinity as Scripture offers, and it matters practically: if Jesus were only partly God, or God’s representative rather than God himself, his death could represent us to God, but it couldn’t actually satisfy the infinite weight of what our sin deserves.

“He is the radiance of the glory of God and the exact imprint of his nature, and he upholds the universe by the word of his power. After making purification for sins, he sat down at the right hand of the Majesty on high,”

Hebrews 1:3 (ESV)

Notice how this verse moves without a pause from cosmic description (“upholds the universe”) to the cross (“purification for sins”). The same person holding the universe together is the one who dealt with sin — a scale of power that makes his sacrifice categorically different from any human offering, however sincere. A finite sacrifice could only ever cover a finite amount; this one is offered by, and therefore carries the weight of, the one who upholds everything that exists.

“There is therefore now no condemnation for those who are in Christ Jesus.”

Romans 8:1 (ESV)

This is the payoff of Christ’s deity, stated as a settled fact rather than a hopeful possibility. “No condemnation” isn’t partial relief or a reduced sentence — it’s a complete verdict, made possible only because the one who paid was capable of paying in full. A limited sacrifice might buy partial forgiveness or temporary peace; only an infinite one can produce “no condemnation,” period.

Hard questions

Did Jesus stop being God when he became a man?

No — Scripture describes the incarnation as addition, not subtraction. Jesus didn’t set aside his divine nature; he veiled its full display and took on a genuine human nature alongside it. Philippians 2:6–8 describes this as Christ “emptying himself” not of deity, but of the outward glory and prerogatives he was entitled to, taking the form of a servant while remaining fully God the entire time.

Is Jesus just as powerful as God?

Yes — because Jesus is God, not a lesser or created being granted power on loan. Colossians 2:9’s “whole fullness of deity” leaves no room for a partial or diminished divinity. Where Scripture describes the Son submitting to the Father’s will, that’s a relationship of role and order within the Trinity, not a difference in essential power, glory, or divine nature.

If Jesus is God, how could God forsake him on the cross?

Jesus’s cry from the cross (“My God, my God, why have you forsaken me?” Matthew 27:46) describes a real, felt experience of separation as he bore the weight of sin the Father was pouring out judgment on. This doesn’t mean the Trinity itself was torn apart — Father, Son, and Spirit remain eternally united in essence — but it does mean something genuinely happened at the cross: the Son, in his human experience, bore an actual forsakenness on our behalf, so that those who trust him never have to.
