However, if you read the verses as "all" meaning "every human being to ever live", it is saying then that every person is saved. Period, end of story. But it's not true in the light of all of Scripture - so there must be something more.
Since the issue is not a sin issue then Christ paid for every human beings sins. The issue has become a Son issue have you believed on the Son, Jesus Christ as your saviour. He paid the price for your sin you must accept that you are sinner and need a saviour who paid the penalty for you. Not all accept His payment, so because their rejection of the Son they will die the second death and be seperated from God forever.
So Christ according to all these verses, When Christ was judged on the cross for sins, He paid for the sins of the entire human race -- not just for the elect.
Romans 5: 6 For when we were yet without strength, in due time Christ died for the ungodly.
2 Corinthians 5:14 For the love of Christ constraineth us; because we thus judge, that if one died for all, then were all dead:
15 And that he died for all, that they which live should not henceforth live unto themselves, but unto him which died for them, and rose again.
19To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation.
Imputation of righteousness occurs here. All who receive has Christ righteousness imputed to their account.
1 Timothy 2:3 For this is good and acceptable in the sight of God our Saviour;
4 Who will have all men to be saved, and to come unto the knowledge of the truth.
5 For there is one God, and one mediator between God and men, the man Christ Jesus;
6 Who gave himself a ransom for all, to be testified in due time.
1 Timothy 4:9This is a faithful saying and worthy of all acceptation.
10For therefore we both labour and suffer reproach, because we trust in the living God, who is the Saviour of all men, specially of those that believe.
11These things command and teach.
Titus 2:11For the grace of God that bringeth salvation hath appeared to all men,
Hebrews 2:9 But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man.
1 John 2:2And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.
