The first thing that someone should be considering is whether the idea of sin is actually real.
If God is supposed to be perfect how could She have made anything or anyone that wasn't perfect.
Think about it. The idea of sin assumes certain things about God that seem highly unlikely.
First it assumes a God who is too incompetent to organize a simple educational field excursion and figure out a way to get all of the students home safely.
How likely is this that God would not be smart enough to come up with a plan for our salvation that is going to work 100 percent of the time?
It also assumes that God must have created us imperfect if we are sinners.
One might assume that God would be able to create someone perfect each and every time if he chose to. Assuming God is capable of this, then it follows logically that we must be perfect creations if we are actually creations of this perfect God.
Unless of course you are saying that God chose to create us imperfect.
If God created us imperfect then anything that may go wrong is Gods fault, not ours. This seems a bit illogical at best so I think that we need to assume that What God creates would have to be perfect.
If this is the case and Gods creations are perfect, then nothing that we can do could change what God created perfect and make it imperfect unless we think that we are more powerful than God is.
How likely is it that we the creation could be more powerful than the creator. I personally find this idea somewhat amusing, and a bit absurd.
Religion tells us that God is perfect. If this is true then it could hardly be logically for Gods creations to be considered to be anything less than perfect.
If this is the case and we are perfect creations of a perfect God then Nothing that we can ever do could possibly change this perfection that God willed, unless we were so powerful that our choices could override and change the will of God.
How likely is that????
Think about it.
