Galatians 3:20

20 Now a mediator involves more than one party; but God is one.

Galatians 3:20 In-Context

18 For if the inheritance comes from the law, it no longer comes from the promise; but God granted it to Abraham through the promise.
19 Why then the law? It was added because of transgressions, until the offspring would come to whom the promise had been made; and it was ordained through angels by a mediator.
20 Now a mediator involves more than one party; but God is one.
21 Is the law then opposed to the promises of God? Certainly not! For if a law had been given that could make alive, then righteousness would indeed come through the law.
22 But the scripture has imprisoned all things under the power of sin, so that what was promised through faith in Jesus Christ might be given to those who believe.
