Now an intermediary implies more than one, but God is one.

Galatians 3:20

The core of Paul's argument here lies in the nature of mediation itself. He's highlighting that a mediator inherently points to two distinct parties needing to be brought together, whereas God's promise operates on a different, singular basis. This subtle distinction elevates God's direct, unilateral promise above any conditional covenant mediated through law.
Now an intermediary implies more than one, but God is one.
English Standard Version (ESV)
Paul is contrasting the Law given at Mount Sinai with God's promise to Abraham, arguing that the Law, mediated by Moses, was a temporary addition. The Law, being a conditional contract requiring human obedience, can't nullify the unconditional promise that came through faith. This verse emphasizes that mediation implies two parties, whereas God's promise originates from Him alone.
Why does Paul bring up the concept of a 'mediator' right here? It seems like a technical point, but it's crucial to understanding the difference between the Law and God's promise.
Paul is drawing a sharp contrast between how God related to humanity through the Law versus how He relates through the promise.
The Law and Its Mediator
The Law, given at Mount Sinai, required a mediator. Think of Moses, standing between God and the people. This immediately tells us something important: mediation implies two distinct parties who need someone to bridge the gap between them. The Law was a form of contract or covenant between God and Israel. It had conditions. If Israel met them, blessings would follow; if not, curses. This kind of relationship, by its very nature, is conditional and depends on both parties fulfilling their roles.
The Promise and God's Oneness
But God's promise, especially the one made to Abraham, is different. Paul says, 'God is one.' This highlights that God's promise isn't a contract between two equal or even distinct parties. It originates solely from God. He is the one initiating, the one guaranteeing. His promise depends not on human performance, but on His own unchanging nature and will. It's a one-sided commitment from God's perspective, though we are called to respond in faith.
If the Law requires a mediator and is conditional, what was its real purpose? Paul argues it wasn't meant to be the path to righteousness.

Paul isn't saying the Law is bad; he's clarifying its role in God's plan.
The Law as a Revealer
Paul explains in the verses leading up to this one (Galatians 3:19) that the Law was 'added because of transgressions.' It wasn't God's original plan for relating to humanity, but an addition made necessary by sin. The Law, with its commands and stipulations, acted like a mirror. It didn't create sin, but it revealed the extent of human sinfulness and the impossibility of meeting God's perfect standard through our own efforts.
The Mediator as a Signpost
The mediation of the Law, therefore, points away from itself and toward something else. It showed people they couldn't keep God's requirements on their own. This created a need – a need for a true Mediator, one who could fulfill the Law's demands and bridge the gap created by sin. This points us directly to Christ, who is the Mediator of a new covenant established not on conditional obedience, but on God's unconditional grace.
The verse highlights the contrast between the conditional, two-party covenant of the Law mediated by Moses and the unconditional, God-initiated promise to Abraham. This distinction is crucial for understanding why faith, not law-keeping, is the basis of salvation.
