Note 4 at Mk. 12:29: Jesus had repeatedly made reference to His deity (see note 1 at Jn. 1:1, p. 2; see note 3 at Jn. 5:18, p. 99; see note 8 at Jn. 5:23, p. 98; see note 23 at Jn. 8:58, p. 234) for which the Jews had sought to kill Him, and yet here He quotes from Deuteronomy 6:4 that "the Lord our God is one Lord." There are note two or three Gods and yet Jesus claimed to be God just like God the Father. This union is a great mystery which the church has come to call the Trinity (Father, Son, and Holy Ghost -- all one Lord; see note 2 at Mk. 1:10, p. 35) that defies human understanding but can be accepted and believed.
