I don't know if I should be joining in debates in this forum, but seriously, how come?
Mods will move this to "Debate with a Calvinist" if they deem it appropriate to do so.
Christ died for sinners, (Romans 5:8), all of us have sinned, (Romans 3:23) so he died for us all.
Context determines meaning. Romans 5 is a key chapter which shows the idea of Surety or Headship. In verse 12 we read "
Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:". Now this illustrates that Adam was the federal head of the human race. When Adam sinned we all sinned in him and so "through the offence of one many be dead". The seed of Adam are dead through being born in sin and conceived in iniquity.
However Christ is the second Adam. Now "as by the offence of one judgment came upon all men to condemnation; even so by the righteousness of one the free gift came upon all men unto justification of life.
For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous." (verses 18 and 19)
This is teaching that the seed of Adam were condemned by their head but the seed of Christ are saved by their head. Hence the "all"s ought be interpreted as regards their head. The seed of Adam is every humanbeing but the seed of Christ is a subset of that. I hope that is clear.
There are several Scriptures which say this;
Correction, "There are several Scriptures which
appear to say this"
John 3:16 - whosoever believes in him shall not perish but have eternal life;
"Whosoever believes" but who will believe? Only those God has given the gift of faith to (Eph 2:8).
2 Corinthians 5:15 -Christ's love compels us because we are convinced that one died for all;
May I suggest
this?
1 Corinthians 15:22 - for as in Adam all die, so in Christ all will be made alive;
Again this ought be interpreted according to Heads as is Romans 5.
2 Peter 3:9 - He is patient with you, not wanting anyone to perish. (And there are no doubt others too, but it's nearly 1a.m and I shouldn't have started this.)
May I suggest John Owen:
"See, then, of whom the apostle is here speaking. “The Lord,” saith he, “is long-suffering to us-ward, not willing that any should perish.” Will not common sense teach us that us is to be repeated in both the following clauses, to make them up complete and full, — namely, “Not willing that any of us should perish, but that all of us should come to repentance?” Now, who are these of whom the apostle speaks, to whom he writes? Such as had received “great and precious promises,”
chap. i. 4, whom he calls “beloved,”
chap. iii. 1; whom he opposeth to the “scoffers” of the “last days,”
verse 3; to whom the Lord hath respect in the disposal of these days; who are said to be “elect,”
Matt. xxiv. 22. Now, truly, to argue that because God would have none of those to perish, but all of them to come to repentance, therefore he hath the same will and mind towards all and every one in the world (even those to whom he never makes known his will, nor ever calls to repentance, if they never once hear of his way of salvation), comes not much short of extreme madness and folly. Neither is it of any weight to the contrary, that they were not all elect to whom Peter wrote: for in the judgment of charity he esteemed them so, desiring them “to give all diligence to make their calling and election sure,”
chap. i. 10; even as he expressly calleth those to whom he wrote his former epistle, “elect,”
chap. i. 2, and a “chosen generation,” as well as a “purchased people,”
chap. ii. 9. I shall not need add any thing concerning the contradictions and inextricable difficulties wherewith the opposite interpretation is accompanied (as, that God should will such to come to repentance as he cuts off in their infancy out of the covenant, such as he hateth from eternity, from whom he hideth the means of grace, to whom he will not give repentance, and yet knoweth that it is utterly impossible they should have it without his bestowing). The text is clear, that it is all and only the elect whom he would not have to perish.”
