Class #20: Abraham “believed God, and it was accounted to him for righteousness” (Galatians 3:6, Genesis 15:6). All of the Old Testament upholds the Scriptural doctrine of justification by grace through faith in Jesus Christ alone. The promise given to Abraham was not that he was to be the father of the Jewish nation. God’s promise was that in Abraham “all the nations/families of the earth shall be blessed” (Gen 12:3, 18:18, etc.). God justifies the people of all nations by faith.
Abraham believed in the promise of the Savior, Jesus Christ, coming from his own body. Abraham’s righteousness was not accomplished by his own works. He was declared to be righteous from faith. Abraham believed that God would create from him “a great nation,” that is the church! The false teachers cannot claim Abraham in support of their righteousness by works. On the contrary, it is the Galatians, who are “of faith,” that can claim Abraham as their father. The believing Galatians are the true sons of believing Abraham.
