Jesus is Truth
Pigs must be flying heh because I'm going to defend MacArthur on this one. See below.
I believe this was to demonstrate salvation in the Messiah. As you said, the fact that the Passover lamb/Lamb died doesn't save. We must do something by faith, which is to apply it to our doorposts/hearts. But I think this touches on MacArthur's point - is it the literal blood we apply to our hearts? If not, what do we mean when we talk about the blood of Jesus?
Personally, I'm not too fond of Stewart's articles. Imo, they tend to be long on sensationalism and short on facts.
But here is JM in his own words responding to the controversy. And then something that seems to make it even more clear. :
