Jesus sure displayed a high degree of confidence about Genesis whenever He talked about it. Works for me.
About the sin of Adam, yes. And His purpose in taking the punishment for that sin, yes. And, you can make the case for the position that the Bible is meant to be literally interpreted in all it's parts. I don't think that's the best case that may be made. Because I also think it does matter what God's creation reveals. OTOH, I don't think that issue affects salvation one way or the other.
But I think that's a big stumbling block for a lot of Christians, especially the ones in college trying to withstand their professor's assaults on their faith.
The reality is, you can be saved regardless of your position on the literalness of Genesis. Believing or not believing in the literal truth of the Garden or not was never listed by Jesus or the Apostles as a condition of Salvation.
So it makes some sense that the core of Christianity, the Resurrection and reality of who Jesus is, has been provided for us with such clarity. Without that, there is no hope or salvation. And all the tools for a reason-based faith are right there for us in scripture.
I had to get to the cross by way of reason. I did not want to be a Christian. I wanted to find a way to avoid having people go to Hell. I couldn't.
But I devoured apologetics for some years as well as the humanist attacks on the Resurrection to find that middle ground. But Christ does not allow any middle ground. So at one point, it all came together so clearly and I found myself gladly on my knees. I had to give up the notion that I had anything to say about how God set things up.
I envy those who get there as easily as you do. My life would have been a lot easier and better had I come to the cross a little more gracefully. But I had to be desperate to lose enough pride to take the step of studying Scripture and apologetics.
