Scripture teaches us to love. Love is directly contrasted with slaughter. To take the life of another is to break the command of love. To fail to help those in need and danger is also to fail to love. No group of people is in more serious danger than the boys and girls in the womb.
Life is victorious over death.
This is one of Scripture's most basic themes. Abortion is death. Christ came to conquer death, and therefore abortion. The final outcome of the battle for life has already been decided by the Resurrection of Christ. It is up to us to spread that victory to every person.
