If we were made to watch a doctor pull off the little baby's legs and arms one by one and place them on the table like a dentist removing cotton from your mouth - if all Americans were made to see what it really is, the pro-life goal of abortion being unthinkable (not just illegal) would be much nearer.
John PiperThe formation of the life of a person in the womb is the work of God, and it is not merely a mechanical process but a work on the analogy of weaving or knitting: "Thou didst knit me together in my mother's womb" (psalm 139:13). The life of the unborn is the knitting of God, and what He is knitting is a human being in His own image, unlike any other creature in the universe... The destruction of conceived human life - whether embryonic, fetal, or viable - is an assault on the unique person-forming work of God.
