The Statement of Barnabas, cited from Clement

Before we believed in God, the corruptible and fragile dwelling of our heart was truly a temple made with hands, when it was full of idolatry and it was the house of demons.  But consider:  the temple of God is being built gloriously.  How?  By receiving the remission of sins and hoping in the name of Christ, let us become new and created anew, because in our dwelling God truly dwells in us.  How?  When the Word of His faith, the calling of His promise, the wisdom of justification, and the commandments of doctrine dwell in us.
