No one is an “accident” and there is no such thing as an “unwanted child”. Every human being is the result of a deliberate, creative act on the part of Almighty God. It is by His will that each human life comes into being and though mother and father may not “want” the child, God does.
Can a mother forget her infant, be without tenderness for the child of her womb? Even should she forget, I will never forget you. –Isaiah 49:15
The hateful acts of rape and incest are certainly terrible terrible circumstances for any child to be conceived under. But God, who is the author of life, is also Love and He creates out of love. Therefore every human being, whether conceived ideally through the intimate and loving union of husband and wife or as the result of a brutal rape, is always the fruit of a Great and Glorious Love!
