And what form will all the aborted babies have?
This is not a novel question. Theologists have grappled with it long before there were elective abortions because of spontaneous abortions, still births and deaths of innocent babies. There is no definitive answer and about this we must put our trust in God.
To make a long story short, God knew us from the foundation of the world and we are made like He is in 3 parts. If a child dies, the spirit and soul will need a suitable body. I believe a fetus that was murdered at 3 months will appear as he/she would at 18-25 or so. That's just me pulling something out of the air as I don't have a Scripture for it. The body is just a container, like a pottery jug to hold water and oil( water and oil is the spirit and the Word of God.) The Potter can make a vase for flowers or a pot for the kitchen to better suit the demand. He will equip us to perform our duties as needed. Jeremiah 18 is a good reading about the Potter and the clay. It is a study on why the clay cannot tell the potter what He is making. There is NOTHING to stop the Potter from throwing the clay into the Potter's field. You don't have a vote on what He makes of you. Frankly, I'll be glad if my garments aren't smoking. I'm standing on the promises that I'm going. I pray that I could be a vessel of honor for Him on Earth.
