A Christian Science perspective.
It seems that confrontation in the world never ceases. Consider the violent sectarian clashes between security forces and militants in the city of Bauchi in Nigeria. The brinkmanship and aggressive rhetoric surrounding North Korea's nuclear weapons tests. The lingering struggles within the ranks of the unity government in Zimbabwe and those endured by Aung San Suu Kyi in Burma (Myanmar).
History has recorded similar confrontations at international, national, community, and family levels for centuries. Some of them are vividly related in the pages of the Bible, where many people proved the superiority of spiritual power over the same kind of physical or political force that still tries to propagandize the world today.
Admittedly, there are those who appear to thrive on confrontation. Others avoid it by walking off and hoping the problem will go away. But God's love alone restores harmony and peace. And from the standpoint of prayer, another type of confrontation is necessary for the purpose of healing.
In facing up to Goliath, the shepherd boy David was not prepared to let the forces of evil – or domination by the anointed but deeply flawed King Saul – dictate the way he thought or acted (see I Sam., chap. 17).
