I think this is the norm. I suspect that there are 2 types responding to an altar call. One type that is caught up in the moment. The other type that came to that moment after a time of reflection on what was missing in their lives.
Yes, that does seem to be the case. My own search ttok several years as well. But there comes a time when Christ makes it as clear as it’s going to get and a decision is made. Just as in this mans case. What an amazing testimony. I am saving it!
