Jesus teaches that God’s will is for a man to be faithful to his wife both physically and mentally; God’s will is for a man to be faithful to his wife in body and soul. This is the true righteousness of Jesus that continues to be true to this day. All of us married men should be striving for this quality of faithfulness with our wives.

The repentance required of the Jewish people was to embrace Jesus as their Messiah and spiritual teacher and break away from the teaching and example of spiritual externalism modeled by the scribes and Pharisees.

Externalism: The belief that what was required by the law was adherence to outward behaviors and rituals rather than inward righteousness.

Jesus was calling Israel back to obeying the Law. In obeying the Law, Israel would be "Salt & Light."

Mosaic Law (Written Law - 613 commandments: moral, civil, ceremonial)
Oral Law (Traditions of the Elders - Detailed rules expanding how to apply Mosaic Law)

The second coming of Jesus and the establishment of His earthly kingdom will be in response to the repentance and reception of the
Tribulation generation of the Jews who will embrace Jesus as their Messiah King (Zech. 12:10-14:21).

Israel's mission was to reveal God to the nations (Deut. 4:6-8). But Israel failed to accomplish her mission because she failed in the three ways the devil will test Jesus. Will Jesus, the new Israel, fail too?
