“Simultaneously JUSTIFIED and a SINNER.” Martin Luther understood that our sin was far too pervasive for us to ever be secure in our salvation if it was based on works. It is only by God’s radical grace that He now looks on us and sees His beloved.
However, even though we are saved, we will still sin in this life. We will still run and still gravitate towards the world. The antithesis still flows strong and steady inside our bones and we do not love the things that God loves. We are prone to wander. However, the concept of alien righteousness can be of great solace. Our comfort can lie in the FINISHED WORK of Christ. It is imputed to us.
2 Corinthians 5:21, “God made Him who knew no sin to be sin for us, so that in Him we might become the righteousness of God.”
