This document provides a lesson on righteousness through faith alone in Jesus Christ. It discusses the three aspects of salvation: justification, which removes sins of the past; sanctification, the lifelong process of spiritual growth; and glorification, when believers will be fully restored to God's image. Righteousness is only obtained through faith in Jesus, not works. One must confess sins to receive forgiveness and be born again. Remaining faithful to God through obedience and bearing spiritual fruit is necessary to retain salvation.
