At the end of chapter 4 Apostle Paul drives home the fact that salvation is not based upon our works, but on our faith in God alone. Abraham is highlighted again as a prime example of that. Righteousness was credited to Abraham as he put his faith in God and His promise. This account was written so we will come to understand that righteousness will be credited to us as well when we put our faith in God and His promise. The key is that we need to continually remind ourselves that our salvation and God’s love for us is not based on our Performance or works, but simply our faith in the very Person and Promise of God.
