What is the relevance to you... of almost a third of the Bible? Is that what you are asking? Why do you think God put this in the Word? Are we only to seek and accept what we deem relevant to us in our own personal approach to scripture? If that is the approach, most of scripture would be irrelevant by your definition, since scripture is not really about you and I , directly. All scripture is profitable and every bit of it is relevant to us ehether we know it or not.
I agree we must honor and respect the Bible in full. The OT foreshadows and warns us. It sets the foundations and rules. Today we feel lost in a world that has so wavered and feels so unsteady.
I remembered reading about Ishmael and its connection to Islam but I overlooked the part about the twins in the womb.
Very enlightening.
