The crusades beginning at the end of the eleventh century was the ultimate display of religious aggression. I have described this time of war as “convert or we’ll kill you” from both sides. Actually it was over territory however both sides used this to convert followers. Belief comes from the inner person, no one can force someone into a belief they do not consider true. There is no historical Biblical account of Abraham of David or anyone else forcing their faith onto anyone. Abraham’s family and even his servants accepted his God because they had witnessed what his God had done for Abraham through his faith. Genesis 15:6, “Abram believed the LORD, and it was credited to him as righteousness.”
