My friend oyster,
There are so many problems with the first post, I don't know where to begin. It's really not worth my time to correct and debate this man. His pastor probably passed along all of that nonsense just as he is doing with the Word of God in our language. I give those posting here benefits of the doubt in God's Word that they are simply repeating that which their pastors told them. I did that too until I did some digging for myself.
I agree with you that our Lord speaks to me through our Bible as he does you. It's not difficult in 98% after getting saved and reading it cover to cover a time or two.
I will look up a conference of a couple preachers discussing this subject for your edification. Please feel free to ask me if you would like any faith building videos or articles on this subject. I hate to see believers faith or unbelievers potential faith to be undermined. Here you go.
