All.

 All have sinned and fall short of the glory of God. This is ENOUGH to condemn every single human being to eternal death. In fact it DOES condemn every single human being to eternal death. (Let me rephrase that just a bit, it condemns every mentally competent human being to eternal death- I'm a firm believer in the very young and mentally incompetent as belonging to God.) 

Our sins condemn us, but we are all, and I do mean ALL are given an opportunity find salvation from that condemnation. Not all opportunities are the same, some are very unique, but all have the chance to accept Christ Jesus as their Savior. 

(Excerpt)

Romans 5:14 Nevertheless death reigned from Adam to Moses, even over them that had not sinned after the similitude of Adam's transgression, who is the figure of Him that was to come. 

15 But not as the offense, so also is the free gift; for if through the offense, so also is the free gift; for if through the offense of one many be dead, much more the grace of God, and the gift by grace, which is by one man, Jesus Christ, hath abounded unto many. 

16 And not as it was by one that sinned, so is the gift; for the judgment was by one to condemnation, but the free gift is of many offenses unto justification. 

17 For if by one man's offense death reigned by one; much more they which receive abundance of grace and of the gift of righteousness shall reign in life by one, Jesus Christ.) 

18 Therefore as by the offense 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. 

19 For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous.

The Reign of Death. 

"Death reigned from Adam to Moses." That does not imply that death did not reign just as much afterwards. But the point is that Moses stands for the giving of the law; "for the law was given by Moses." John 1:17. 

Now since death reigns through sin, and sin is not imputed when there is no law, it is evident from the statement that "death reigned from Adam to Moses," that the law was in the world just as much before Sinai as it was afterwards.

"The sting of death is sin; and the strength of sin is the law." 1 Cor. 15:56.

There can be no sin imputed when there is no law; but wherever there is sin, there death reigns.

Adam a Figure. "Death reigned from Adam to Moses, even over them that had not sinned after the similitude of Adam's transgression, who is the figure of Him that was to come." 

How is Adam a figure of Him that was to come, namely, Christ? Just as the following verses indicate, that is, Adam was a figure of Christ in that his action involved many besides himself. It is evident that Adam could not give his descendants any higher nature than he had himself, so Adam's sin made it inevitable that all his descendants should be born with sinful natures.  Sentence of death, however, does not pass on them for that, but because they have sinned.

A Figure by Contrast. Adam is a figure of Christ, but only by contrast. "Not as the offense, so also is the free gift." Through the offense of one many are dead; but through the righteousness of One, many receive life. "The judgment was by one to condemnation, but the free gift is of many offenses unto justification. "For if by one man's offense death reigned by one; much more they which receive abundance of grace and of the gift of righteousness shall reign in life by One, Jesus Christ." There is contrast all the way through. Everything that came through Adam's fall is undone in Christ; or, better still, all that was lost in Adam is restored in Christ.

"Much More." This might be taken as the key-note of this chapter. Not only is everything that is lost in Adam restored in Christ, but "much more." "If, when we were enemies, we were reconciled to God by the death of his Son; much more, being reconciled, we shall be saved by his life."

And there is no chance of finding fault with the inevitable fact that we are inheritors of a sinful nature through Adam. We can not complain that we are unjustly dealt with. It is true that we are not to blame for having a sinful nature, and the Lord recognizes the fact. So he provides that just as in Adam we were made partakers of a sinful nature, even so in Christ we shall be made partakers of the divine nature.

But "much more." "For if by one man's offense death reigned by one; much more they which receive abundance of grace and of the gift of righteousness shall reign in life by One, Jesus Christ." That is, the life of which we are made partakers in Christ is much stronger for righteousness than the life which we received from Adam is for unrighteousness. God does not do things by halves. He gives "abundance of grace."
