Jesus’ Words are the truth and by them the Holy Spirit works faith in those who hear. Faith is what receives the forgiveness of sins. Bearing this in mind, we confess from the Old Testament reading that since the Lord has saved us from sin through His Word, we teach it to our children so that they may be saved, too.
The Law, with its thunder and lightning, was set in place to show us our sins and bring us to repentance. Yet, the Lord promised through Moses – and has made good on it – another Word, the Word of Gospel. By the Good News of Jesus’ birth, life, death, and resurrection, we are set free from sin and we will live eternally with Christ, our Lord and brother.
