"He is the One who made it possible to have kids through DI, the doctors are just a vessel to accomplish this great thing. If God had not wanted me to have kids through DI, He would not have let me get pregnant twice and carry both kids to term."What this mom is really saying is: "God let it happen, therefore it must be okay."
Unfortunately that argument doesn't work, because that's not how God works. As everyone has observed in this life, God lets bad things happen all the time. Let's see:
- Illness, suffering and death
- War, famine and natural disasters
- Murder, theft, rape, incest, pedophilia, and all the crimes committed by men against one another
God doesn't stop these things from happening. Does this mean God thinks they are moral? Does it mean God wants them to happen?
Often, criminals benefit from their crimes (for example, they get rich by stealing). Occasionally, children are even born as a result of rape. Does this mean that rape is "moral" because God "made it possible" to have a child through the rape?
This argument just doesn't work.
The fact is, God allows us to do both moral and immoral things, because he gave us free will. We can use science for good or for evil. And strangely, God will allow good things to come from bad things: for example, he will allow rape to bring forth a new, innocent human life. Yet this doesn't ever make the rape good.
We can use science for good ends or bad ends. God will let us create babies and kill them. God will let us create babies and take them away from their parents. We can do lots of bad things, and God will let us. But that doesn't ever mean that he approves, or that he thinks this is moral.
