I wonder how many generations have said "the way things are im not sure I want to bring children into the world"?
i think a lot of people have been saying that since the last century because it has been the most violent worldwide, two world wars, nuclear weapons, large scale poisoning...political instabilty
Unless God give us the go ahead (he did for the Israelites when they were exiled to Babylon) sometimes its not prudent to raise a family in the midst of war, captivity or apartheid. Ask the Red Cross or save the children...or any of the relief agencies.
As christians we do seek to be the peacemakers, not the warmongers. So if we actively seek peace, we need to take steps to ensure it is a world where children can sleep at night, safe in their own beds.
