“[L]et us draw near with a sincere heart in the assurance that faith brings, because we have had our hearts sprinkled clean from an evil conscience and our bodies washed in pure water.”
Our faith is sure because we have had the objective experience of inner cleansing in baptism. God said to do this in faith and repentance and our sins would be washed away. We believe him. Let us then go to him.
Baptism is more than a symbol. In immersion something really happens. Christ’s blood purifies us from sin, when we obey in faith. Do you believe this?
