"Church or religion cannot save us?"
The true Church is not the Savior or will not be the one who will save us, the Lord Jesus is the Savior. However, who will the Savior (the Lord Jesus Christ) will save?
Ephesians 5:23 TEV
“For a husband has authority over his wife just as Christ has authority over the church; and CHRIST IS HIMSELF THE SAVIOR OF THE CHURCH, HIS BODY.”
