God gave some...

John 17:6 "I have manifested Your name to the men whom You gave Me out of the world; they were Yours and You gave them to Me, and they have kept Your word. 7 "Now they have come to know that everything You have given Me is from You; 8 for the words which You gave Me I have given to them; and they received them and truly understood that I came forth from You, and they believed that You sent Me. 9 "I ask on their behalf; I do not ask on behalf of the world, but of those whom You have given Me; for
they are Yours; 10 and all things that are Mine are Yours, and Yours are Mine; and I have been glorified in them.

20 "I do not ask on behalf of these alone, but for those also who believe in Me through their word; 21 that they may all be one; even as You, Father, are in Me and I in You, that they also may be in Us, so that the world may believe that You sent Me. 22 "The glory which You have given Me I have given to them, that they may be one, just as We are one; 23 I in them and You in Me, that they may be perfected in unity, so that the world may know that You sent Me, and loved them, even as You have loved Me.

Did Jesus Christ give His life a sacrifice for all men's sins or the sins of those God gave Him? And not only the elect that were there with Him, but all of the elect in Jesus' "past," present and "future"...
