As I understand the doctrine as Calvinist teach it, they would say it is sufficient for all mankind. Sufficient for all, efficient for the elect. We need to be careful not to misrepresent the doctrine you disagree with. If it is wrong, one should be able to accurately say what it is and say why they disagree with it.
I've read the definition from many reformed. It tends to be different depending on who you talk to, but I have yet to see a reformer say Christ died for all mankind.
apples and oranges. You would die to save your wife's life, as would I. Jesus died in our place of punishment.
I don't think so. Giving up one's life for another is the issue, out of love. The reason is secondary.
Let me ask you this. Would you send your wife or children to hell? All those that reject Christ will spend eternity in hell. If your child disobeyed you and they refused to repent, would you send them to hell?
Now THATS apples to oranges

A more accurate analogy would be as a judge, would I send my son to prison if he were guilty of a crime. Although I love him, justice demands I do just that.
Hell is a place for sinners. It is punishment. God will send them there to pay for their sins. God is under no obligation to save anyone. Your argument acts like God is obligated to save and He is not.
He is obligated to save those of faith since it's His requirement. People don't go to hell to pay for their sins...a finite man can never repay an infinite God for an infinte crime committed against Him. That leaves God eternally unpaid for the crime. That is the point of Christ being the only one who CAN repay and appease God's wrath ultimately leading to true justice being had.
The following is from a fellow BB member Allan. He did a good job of explaining the scope of the atonement, so I'll just copy it below...
1 John 2:2 states He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world. You need to go back and see how John uses "whole world" in his letters. He always means "all sinful mankind" in his usage. While John does use the term 'world often and it has 3 basic meanings and of those three 'base' meanings variations of them can be noted. (1) World (as in earth itself), (2) Geographically specific to a place or world system (ie. Roman world), and (3) all sinful wicked men.
*NOTE* World NEVER refers to believers. A word can not have two contradicting meanings (ie. yes can not mean both yes and no. Just as saved does not mean both saved and lost) Believers are not of this world, we are called to be seperate from the world and to come out from amoung the world, ect.. and at the same time be said to 'be the world'.
The OT established the meanings and the NT continued it and does not contradict it. When scripture is speaking of the spiritual state of people the term 'world' always refers to the sinful wicked men. John also used the phrase 'whole world' and while it's meaning regarding the spiritual state of men does not change it's scope does. Just for review here is everytime John uses this particular phrase:
Quote:
1Jo 2:2 And he is the propitiation for our sins: and not for ours only, but also for [the sins of] the whole world.
1Jo 5:19 [And] we know that we are of God, a\nd the whole world lieth in wickedness.
Rev 12:9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
Rev 16:14 For they are the spirits of devils, working miracles, [which] go forth unto the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty.
It is of note that John uses the phrase 'whole world' four times, twice in two different books he writes. In each instance we plainly see that John holds this phrase to be used in only one way - whole world = sinful wicked men. The term 'whole world' encompasses not only the gentiles, in which the term 'world' alread speaks to, but 'whole world' includes both the Jews and Gentiles as one group instead of Christ dying only for those of the Jewish Nation
