“Wherefore then serveth the law? It was added because of transgressions, till the seed should come to whom the promise was made; and it was ordained by angels in the hand of a mediator.”
My Notes
What Does Galatians 3:19 Mean?
Paul asks the question the Galatians must be thinking: if salvation is by faith, what's the point of the Law? His answer: the Law was added because of transgressions — to expose them, define them, and restrain them — until the promised Seed (Christ) would come. The Law was temporary by design. It had an expiration date: "till the seed should come."
The phrase "ordained by angels in the hand of a mediator" describes how the Law was given: through angelic intermediaries, with Moses as the mediator between God and the people. Paul is making a subtle point: the Law came indirectly (angels → mediator → people). The promise came directly (God → Abraham). The directness of the promise exceeds the mediated nature of the Law.
The Law wasn't a mistake. It was a bridge — a temporary structure designed to function between the promise and its fulfillment. You don't live on a bridge. You cross it. The Law carried Israel from Abraham to Christ. Now that Christ has arrived, you step off the bridge.
Reflection Questions
- 1.How does understanding the Law as temporary (a bridge, not a destination) change your relationship to Old Testament commands?
- 2.Where are you still 'living on the bridge' — relying on the Law for something only Christ can provide?
- 3.Does the idea that the Law exposed sin rather than fixed it change how you read the Old Testament?
- 4.How do you honor the Law's purpose (it was necessary) while accepting its completion (Christ has come)?
Devotional
What's the Law for? If faith is what saves you, why did God bother with Sinai?
Paul's answer is surgical: the Law was added because of transgressions. Not to fix them — to expose them. To give sin a name. To draw a line so you could see that you'd crossed it. Without the Law, sin existed but was undefined. The Law made it specific, visible, and undeniable.
And it had an expiration date: "till the seed should come." The Law was never meant to be permanent. It was a temporary structure — a bridge between the promise to Abraham and the fulfillment in Christ. You don't live on a bridge. You cross it. And when you reach the other side (Christ), you step off.
The Law came through angels and a mediator. The promise came directly from God to Abraham. Paul is showing the hierarchy: the more direct the communication, the more fundamental the covenant. The promise is older, more direct, and more permanent than the Law. The Law served the promise, not the other way around.
If you're still living on the bridge — still trying to use the Law as the foundation of your relationship with God — Paul says: the seed has come. The bridge served its purpose. Step off. Not into lawlessness. Into Christ. The destination the bridge was always carrying you toward.
The Law was necessary. The Law is finished. Both are true.
