It is evil to justify killing (unborn babies) by the happy outcome of eternity for the one killed. This same justification could be used to justify killing one-year olds, or any heaven-bound believer for that matter. The Bible asks the question: "Shall we sin that grace may abound?" (Romans 6:1) And: "Shall we do evil that good may come?" (Romans 3:8). In both cases the answer is a resounding NO. It is presumption to step into God's place and try to make the assignments to heaven or to hell. Our duty is to obey God, not to play God.
John PiperDo you feel loved by God because you believe he makes much of you, or because you believe he frees you and empowers you to enjoy making much of him?
John PiperBut whatever you do, find the God-centered, Christ-exalting, Bible-saturated passion of your life, and find your way to say it and live for it and die for it. And you will make a difference that lasts. You will not waste your life.
