God Is One - Galatians 3:19-20

Galatians 3:19-20 ESV 

Why then the law? It was added because of transgressions, until the offspring should come to whom the promise had been made, and it was put in place through angels by an intermediary. Now an intermediary implies more than one, but God is one.

The offspring is Christ. To Him the promise is made. All those in Christ receive that promise. We are one with Christ who is one with the Father. We are united by the Holy Spirit. 

The law was given by an intermediary, that is Moses. God wrote the law on stone tablets, gave them to Moses who brought it to the people. 

An intermediary is not used in the fulfillment of the promise. It is put in place by the Father, Son, and Holy Spirit who are one. The way of God is written on our hearts because the very Spirit of God dwells there. The language used is the living word of God. We comprehend this life as the Son and Spirit of God, with Whom we are one. 

God is one and so are we.
