For in the gospel a righteousness from God is revealed, a righteousness that is by faith from first to last, just as it is written: “The righteous will live by faith.”
In “Credited as Righteousness” we saw that Abraham believed God and it was credited to him as righteousness. In Romans, Paul continues this teaching.
The righteousness that we have is not our own but rather it is given to us from God. We don’t earn it but instead it is given to us because of our faith. Once we have been given righteousness, we continue to live by faith.
Many Christians mistakenly follow the Lord out of duty because of the laws of God. We can’t live up to the standards of God though; the Old Testament showed us this clearly. That is the whole reason that Jesus had to come to earth as a sacrifice for us.
Christians, the righteous in this case, live by faith not out of duty but out of love. We were given righteousness on account of our faith. We don’t continue to live by faith in order to maintain our righteousness though. We continue to live by faith because we have been made righteous.
Christians should want to follow the commands of God, not feel duty bound to observe them. Without a doubt, our sinful nature is going to continue to rebel against God and we’re not always going to do what is right. We’re not even always going to want to do what is right. But in the end we should live by faith simply because we want to please the Lord.
