God is the fountain of life. How does he give us life? He creates us, sustain us while we are on earth, and gives us eternal life in heaven if we believe in him. How can we possibly brush aside this most wonderful offer and promise? If we destroy life such as that of the unborn on earth, we destroy our own eternal life. After we die, we'll have no more power to alter our course. We have only one limited lifetime to set our eternal destiny.
