If so, he should have referred you to their works which would have provided a more convincing answer. He does not, however, refer you to any such works. Instead, he supports his argument with his own personal experience. I find that in conflict with the Islamic approach. It is indeed the Christian way of thinking.
Christians always speak about saying their experience with others in order to preach their faith.
But your experience can never give me the same feelings as yours or help me arrive at the same conclusions. Furthermore, when you realize that the same experience can have totally different effects on people, you are bound to conclude that experience is not sufficient to propagate beliefs. In Islam, we have the fundamentals of our faith clearly stated in the Qur'an and elaborated and stressed by the Prophet. The examples presented by your relative are of little value. What he implies is that a medium is essential for the accomplishment of any task, even eating.
