...this fellow may need to be compelled by the internal consistency sustained between the Old and New Testaments.
Best wishes, if you can persuade him that there is such a consistency.
If he is familiar with the Old Testament statement, "Out of Egypt have I called my son",he will know that this is a reference to Israel coming out of Egypt. So how are you going to explain to him that the statement is used in one of the gospels as a prophecy that Mary and Joseph fled with Jesus to Egypt, and later came "out of Egypt".
When told that antifreeze is poison, do you believe the testimony or do you drink some to find out? We live our lives in the secular sense by faith, why should it be otherwise in religion?
Because knowing where we will appear in the next life is so much more important than knowing that antifreeze is poison!
We believe what we read or are told by faith, based on the trustworthiness of our source.
Consider the following true story. A teacher told her class of a tribe of people who lived on a remote island. She pointed out on a map where the island was located. She told them that the people were mean, dirty, lazy, and used many even more negative terms to describe them. By this means, she actually taught the pupils to hate the tribe.
As it turns out, it was all a sociological experiment. The island and the tribe did not exist!
If a teacher is not a trustworthy source, who can we beleive? Even trustworthy sources sometimes fail us.
Scientists tell us that there is an infinite regression of time into the past.
I believe that time actually had a beginning, that the phrase "in the beginning" (Genesis 1:1 and John 1:1) actually refers to the beginning of time, and that were no events before this (because there was no "before").
Scientist tell us that all life evolved from a simple cell or cells that "appeared" in the sea.
I believe that "God created the heavens and the earth and all that in them is."
No. The "trustworthy sources" are not always worthy of our trust.
