Bible based Decision

Although I was not present, a guest pastor told to our church about Abraham, his order to sacrifice Isaac and how he proceeded. The pastor took lessons from the text such as: do not question the Lord's order. 

Certainly, it shocked a physician and professor with a sharp mind that is in his 70's. For him, this kind of sermon would lead a lunatic to make atrocities in God's name.  How to avoid it? He put it as a debate in Sunday School to listen and take his conclusions.

I told that Bible reading and prayer should guide the christian. The World of the Lord is light to the feet of the believer. A lot of people are misled due to lack of knowing the Word, lack of prayer, and their own greed.
He was not very satisfied with this answer. I think that he wants to dissect the reasoning of the guest pastor and his conclusion. In some way he is right. There are many conclusions based on small excerpts from the scripture that are not sustained by a more meticulous approach.
