My verse? Gee, I didn't write it, I just quoted it.
So far you have not given a single verse that says that not one drop of Christ's blood was shed in vain.
It would appear that the "universal atonement" verses outnumber the "limited atonement" verses about 2 to 1, maybe even 3 to 1 . And so far you have no bumper sticker verses to back up your bumper sticker slogan. If you find one, let me know. John 10:15 just doesn't cut it. It does not necessarily mean what you (by your slogan) claim it means .
P-Marlowe, I think you are just being argumentative for argumentativeness sake. I gave you my verse. You clearly don't believe in effectual atonement, and I do. I don't do bumper stickers. That was your phrase. The Bible doesn't contradict itself. Jesus died for the sheep. His blood doesn't pay for the sins of those who don't believe. His blood reaches its intended target.
