Romans 4:25 says He was delivered for our offenses and raised for our justification. If He was resurrected for everyone, then you have a whole bunch of justified sinners in hell, no?
No, not at all. The "our" means the world.
Why imply it refers to believers? If you are going to interpret it that way, then one might be justified in the interpretation that Paul is writing to the Romans and it applies only to the Romans and not to you at all.
What about Psalm 23:1. "The Lord is my shepherd." Is the "Lord" only the shepherd of David? That is what it says, and according to the Calvinistic way of interpretation being espoused here that is what it must be limited to. He can't be your shepherd too, for that is not what David said.
In Acts 20:28
Act 20:28 Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood.
--Paul is speaking only to the church at Ephesus. He purchased the believers of the church of Ephesus with his own blood--no other church, no other believers, but them. It refers just to them. This verse was directed only to the Ephesian elders mentioned in verse 17:
Act 20:17 And from Miletus he sent to Ephesus, and called the elders of the church.
--It is not applicable to you.
This is the Calvinistic method of interpretation.
Thus when it comes to verses like John 3:16, where God so "loved the world" the "world" must not be the "world" in total, just like the Ephesian church can't represent other churches. You must be consistent in your interpretation. If the "world" must have a limited definition of the elect, then the Ephesian church must also have a limited definition, as also David's Lord in Psalm 23:1.
But I am thankful that I am not constrained by such a limited interpretation of God's Word.
Tell me, how many people does God love? How extensive is God's love?
Gal 2:20 I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God,
who loved me, and gave himself for me.
--Sorry, he left you out. His love was limited to Paul alone. If he didn't love you, you are not one of the elect. This makes the case for election very easy. Paul is the only one--according to Calvinistic logic.
Therefore:
Romans 5:19 For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous.
--Were many made sinners or were all made sinners?
Romans 5:15 But not as the offence, so also is the free gift. For if through the offence 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.
By the offence of one, were many dead or all dead?
Likewise, did the grace of God which came by one man, was it available to many or to all?
The answer is more clearly given:
Romans 5:18 Therefore 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.
--It simply must be received. All means all. It does not simply refer to the elect.
The resurrection also if for all.
1Co 15:20 But now is Christ risen from the dead, and become the firstfruits of them that slept.
1Co 15:21 For since by man came death, by man came also the resurrection of the dead.
1Co 15:22 For as in Adam all die, even so in Christ shall all be made alive.
--All died; all will be made alive; some to eternal life; others to eternal death.
