One reason why Jews didn't accept Jesus.

121: 7.1 (1339.6) By the times of Jesus the Jews had arrived at a settled concept of their origin, history, and destiny. They had built up a rigid wall of separation between themselves and the gentile world; they looked upon all gentile ways with utter contempt. They worshiped the letter of the law and indulged a form of self-righteousness based upon the false pride of descent. They had formed preconceived notions regarding the promised Messiah, and most of these expectations envisaged a Messiah who would come as a part of their national and racial history. To the Hebrews of those days Jewish theology was irrevocably settled, forever fixed.

121: 7.2 (1339.7) The teachings and practices of Jesus regarding tolerance and kindness ran counter to the long-standing attitude of the Jews toward other peoples whom they considered heathen. For generations the Jews had nourished an attitude toward the outside world which made it impossible for them to accept the Master’s teachings about the spiritual brotherhood of man. They were unwilling to share Yahweh on equal terms with the gentiles and were likewise unwilling to accept as the Son of God one who taught such new and strange doctrines.
