The third article of the Apostles Creed and it’s meaning.
The Third Article: Sanctification
I believe in the Holy Spirit, the holy Christian church, the communion of saints, the forgiveness of sins, the resurrection of the body, and the life everlasting. Amen.
What does this mean?
I believe that I cannot by my own reason or strength believe in Jesus Christ, my Lord, or come to Him; but the Holy Spirit has called me by the Gospel, enlightened me with His gifts, sanctified and kept me in the true faith. In the same way He calls, gathers, enlightens, and sanctifies the whole Christian church on earth, and keeps it with Jesus Christ in the one true faith. In this Christian church He daily and richly forgives all my sins and the sins of all believers. On the Last Day He will raise me and all the dead, and give eternal life to me and all believers in Christ.
This is most certainly true.
