If we look at the great speech of Moses in Deuteronomy - Hear O Israel ... There is first an emphasis on who God is, God the person who led them out, then on God being one person, one God, and then on how to show love to this one person who is God of Israel by keeping this God’s words and giving them high prominence in daily life and teaching them to children to persist them through future generations. It is practical love based on truth. It was possibly the greatest sermon in history, until the Sermon on the Mount. The Sermon on the Mount does not replace it at all, but augments it and completes it. The Sermon on the Mount is in perfect continuity with the Moses Hear O Israel sermon, and Jesus maintained the focus of Moses on “Your God” by then continuing by referring to this same one God as “Your Father in Heaven”. Hence One God becomes in Jesus’ teaching the One True God, the Father.
