What Is the Christian Life?

These two are the first elements of Christian life: Repentance or contrition and grief, and faith through which we receive the forgiveness of sins and are righteous before God. Both should grow and increase in us. The third element of Christian life is the doing of good works: To be chaste, to love and help the neighbor, to refrain from lying, from deceit, from stealing, from murder, from vengefulness, and avenging oneself, etc.
