The Jews are messengers to humanity as chosen by God in that they were one of the first communities to not only encounter the phenomena of the gaps in the genius of human behavior(other civilizations encountered it and had rules for their cities and towns) to be observed in the proximity of various humans and human families as witnessed in their own community in Egypt (where such proximity existed on mass for the first time) but, they were the first to prayerfully commit to building an ark of rules to be kept prayerfully with the help of God's spirit. Natural law existed and was exercised in small community and familial settings by the Jewish Patriarchs in their families and in family squabbles as seen in the experiences of Abraham and his descendants. The ark of rules( a codification of natural law) is an ark to provide a wall of civilization against the flooding gap that can overwhelm civilization if such an ark of rules to preserve civilization did not exist. Noah was a prophet who encountered a flood. Lot encountered a flood of fire. It was a similar experience in light of an unfortunate gap in the genius of human behavior. The solution other than floods of fire and water is an ark of rules and prayer maintained by the power of the Holy spirit. As such, the gap is filled with the bounty of the Holy Spirit. MIND THE GAP.
