No no. You are too much into biology. This is beyond biology.
In this case, biology is also the actions of God, so we can look at biology to test whether your
theological hypothesis is correct.
God creates a human spirit and God wants it to go to a human flesh. So, God make a particular sperm go to a particular egg. Then we have a new life.
That is contradicted both by God's Creation (biology) and theology. Remember, there are millions of sperm released and
hundreds of sperm get to the ovum. If God acted by having only one sperm destined to get to the ovum, then we would release only one sperm.
On the theological side, you still have a soul in a sperm and a soul in an ovum. That makes
2 souls. No one in theology has ever discussed
half souls such that two half souls have to combine to make a whole soul.
If you say that God directs which sperm to which ovum, you have made God
directly responsible for
all birth defects. C'mon, if God is going to pick the sperm to go with the ovum, then God knows the genetic composition of each and knows what the result is going to be when they combine.
This confirms the problem of evil, which is one of the better arguments for atheism, or at least one of the better arguments for not
worshipping God. It is impossible to believe in a "loving" God if God deliberately and directly subjects some individuals to horrific birth defects. Such a god may exist but that god is certainly not worthy of worship. At best, we could view it as a satanic god to fight against.
So, rather than discard the standard belief about God being loving and just, I am going to discard your hypothesis about when a soul is infused. Instead, I am going to go with the hypothesis that God infuses a soul somewhere between conception and birth.
Something else just occurred to me. We are starting to get into treatments involving genetic diseases. For instance, a transfusion of adult mesenchymal stem cells (MSCs) is being used to treat osteogenesis imperfecta. By your hypothesis God
wanted that person to have OI. Afer all, you said "God wants it to go to a human flesh". By your hypothesis, this treatment would be thwarting the will of God. Rather than obeying the Great Commandment and trying to help the individual, your hypothesis would make this treatment disobedience of God. How many parents and people with OI do you think this is going to drive
away from God?
Juvenissun, I think you throw ideas out there just to stir up trouble. However, you need to start thinking about the
consequences of those ideas. Not only is the behavior juvenile, but it also borders on outright evil. If you are serious about your Christianity, you should not want to throw ideas out there that are going to harm God and prevent people from finding Him.
