While there are illegitimate parents, there are no illegitimate children. Many children are unplanned by their parents, but they are not unplanned by God. God's purpose took into account human error, and even sin. God never does anything accidentally, and he never makes mistakes. He has a reason for everything he creates, every plant and every animal was planned by God, and every person was designed with a purpose in mind. God's motive for creating you was love.
—Rick Warren, The Purpose Driven Life
