Read: Romans 4
“A clear understanding of this idea that we are counted righteous on the basis of Christ’s righteousness and not on our own obedience is crucial for our confidence that we are right with God and that God therefore accepts us and is looking upon us in favor. If assurance of God’s favor was based upon our works, we could only have assurance if we were perfect. That means that there can be no assurance if our acceptance with God is based on our works. But if we understand the gospel we can have that assurance because Jesus’ work is perfect, and his perfect righteousness is credited to us.”
