They invaded an already occupied land and systematically killed its inhabitants. And they did so at God's direction. Sometimes people become so wicked the only solution is to make war upon them. OK, so I mixed both questions together. Faith doesn't produce a helpless surrender to evil and evil men.
Faith makes good men brave and honorable men courageous.
He has called holy men from the time of Abraham and throughout holy history to defend the defenseless and to press the cause of justice into the camp of the enemy. Lord, thank you for the ministry of preservation you have given to us soldiers. Bless our men and women in uniform today. Use our hands to bless Kosovo's refugees.
