It doesn't make any sense to say, "Jesus knew from all eternity past, before Adam was created, that Goliath would reject faith in Christ, but yet Jesus went ahead and died for Goliath in an divine but failing attempt to save him".
In sarcasm, but in analogy, I sent a check for $5,000 along with 10 books, 10 videos, and 100 mp3s to Pharaoh's tomb, in an attempt to get him to let the jewish slaves free, and spare himself the coming plagues.
