Thematic Bible: How death entered into the world

But in reality Christ has been raised from the dead, the first to be raised of those who have fallen asleep. For since it was through a man that death resulted, it was also through a man that the resurrection of the dead resulted. For just as all men die by virtue of their descent from Adam, so all such as are in union with Christ will be made to live again. read more.
But each in his proper order; Christ first, then at His coming those who belong to Christ.

So here is the comparison: As through one man sin came into the world, and death as the consequence of sin, and death spread to all men; because all men sinned. Certainly sin was in the world before the law was given, but it is not charged to men's account where there is no law. And yet death reigned from Adam to Moses, even over those who had not sinned in the way Adam had, against a positive command. For Adam was a figure of Him who was to come. read more.
But God's free gift is not at all to be compared with the offense. For if by one man's offense the whole race of men have died, to a much greater degree God's favor and His gift imparted by His favor through the one man Jesus Christ, has overflowed for the whole race of men. And the gift is not fit all to be compared with the results of that one man's sin. For that sentence resulted from the offense of one man, and it meant condemnation, but the free gift resulted from the offenses of many, and it meant right standing. For if by one man's offense death reigned through that one, to a much greater degree will those who continue to receive the overflow of His unmerited favor and His gift of right standing with Himself, reign in real life through One, Jesus Christ. So, as through one offense there resulted condemnation for all men, just so through one act of uprightness there resulted right standing involving life for all men. For just as by that man's disobedience the whole race of men were constituted sinners, so by this One's obedience the whole race of men may be brought into right standing with God. Then law crept in to multiply the offense. Though sin has multiplied, yet God's favor has surpassed it and overflowed, so that just as sin had reigned by death, so His favor too might reign in right standing with God which issues in eternal life through Jesus Christ our Lord.
