Be hospitable one to another without grumbling.
Now this is the same rationale that Paul had in Romans chapter six. As far as baptism is concerned, as far as my old man being crucified with Christ, dead, buried in the water of baptism; as I come up it's the resurrection, it's the new life in the Spirit. And they who are really living the new life in the Spirit have ceased from sin. Paul said, "How are we, who are dead to sin, going to live any longer therein" ( Romans 6:2 ). John tells us in his epistle, and we'll be getting that a couple of weeks, that "whosoever is born of God does not practice sin" ( 1 John 3:9 ), because we have God's seed now in us. We've been born again by the Spirit of God and we cannot practice sin.
