What “reproach” where does that come from? Did you know that Jesus was the atonement for our sins ON THE CROSS? He died on the cross as a living sacrifice for OUR sins. We are saved if we believe in Him as the Son of God . John 3:16-18, Go read it. “Reproach” my eye. What a joke.
Don’t understand your anger as MacArthur is quoting scripture; “reproach of Christ “ is in the Bible.
