He came not to bring the peace of this world, which is only that we don't bother each other. He came to give the peace of heart, which comes from loving - from doing good to others.
While still in the womb of the Virgin Mary, Jesus brought peace to John the Baptist who leapt for joy in the womb of Elizabeth. I feel that the greatest destroyer of peace today is abortion because Jesus said: "If you receive a little child you receive me." So every abortion is the denial of receiving Jesus."
We must persuade her [the Mother] with love, and love means to give until it hurts. Jesus gave even His life to love us. So, the Mother who is thinking of abortion should be helped to love, that is, to give until it hurts, her plans, her free time, to respect the life of her child. For the child is the greatest gift of God to the family, because it has been created to love and to be loved. The father of that child however, must also give until it hurts.
So abortion just leads to more abortion.
Any country that accepts abortion is not teaching it's people to love one another, but to use any violence to get what they want. This is why the greatest destroyer of love and peace is abortion.
