new hope, there is nothing that justifies it. Nothing.
Try to put the murdered or the drowned children in the equation of choosing "salvation, accepting jesus as your personal savior". It doesn't fit that theology.
The practical imperative to love others is far more compelling if we are to be the living arms of Jesus. If he overcame the world, then he did it not with theology but by showing us how to live lovingly in spite of it. Reach out to the broken-hearted and the ones in prison....
I do not see any justification for the horror and misery of children.
