Conflict is deeply embedded in the human heart and the entire history of salvation. The entire Bible from Genesis to Revelations is an endless series of conflicts between God and the evil spirit, between good and evil, love and hate, and heaven and hell.
St. Paul writes that there is a fight in my heart between good and evil. In every healthy community, there are differences of opinion which can result in conflict, confrontation, and a fight for the dominance of opinions and views. The Gospel includes the never-ending conflict of Jesus with the Pharisees.
Jesus did not seek this conflict, but by preaching the Gospel, He provoked people to stand for the truth, and this always results in conflict.
