1. Yes.
Death IS the judgement of God toward the sin of man. This judgement has passed on to every man regardless of what he might know about it. This is taught in
Rom 5:12 Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:
Rom 5:13 (For until the law sin was in the world: but sin is not imputed when there is no law.
Rom 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.
Notice the logical argument made by Paul. Even though there was no "written law" revealed through Moses.....Death reigned over man from Adam to Moses. Thus proving the "judgement of sin" still had effect regardless of one might think about the "imputation of sin". Even those who did not "sin" in the same manner in which "Adam" himself sinned. This illustrations proves that traditional doctrine of "original sin" and its effects on MANKIND.... or the offspring of Adam. God did not just judge Adam. He judged Adam and all his offspring. Regardless of what you think about the imputation of sin, the fact everyone "DIES" proves God's judgement extends to all of mankind. Even those who did not choose to "sin" like Adam did.
2. God is just in that He has included ALL UNDER SIN.
Rom 3:9 What then? are we better than they? No, in no wise: for we have before proved both Jews and Gentiles, that they are all under sin;
Rom 3:10 As it is written, There is none righteous, no, not one:
Rom 3:11 There is none that understandeth, there is none that seeketh after God.
Rom 3:12 They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.
There are no SPECIAL cases in which God has determined anyone exempt from his JUST decree.
3. You're looking at this the wrong way. You can't be saved through looking at creation. You can ONLY be saved through Christ. Paul made the argument in Romans 1 that mankind has no excuse to deny the existence of God. He recorded the FACT that that those of old KNEW HIM AS GOD. Yet, they DENIED HIM. The same can be said of anyone. The handy work of God in all of creation itself demands that everyone recognize the existence of SOMEONE greater than themselves.
If you recognize the existence of a "creator". Surely one should seek to find out who that Creator IS. This is taught in
Act 17:26 And hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation;
Act 17:27 That they should seek the Lord, if haply they might feel after him, and find him, though he be not far from every one of us:
Now some would argue man can not seek after God but that is total nonsense. Act 17 and Paul's sermon PROVE differently. Don't listen to those that say differently. The Scriptures are true regardless of what anyone thinks of them.
Even John Gill (one of the most learned Calvinist that ever lived) really gave a silly response to such a verse when he wrote.
if haply they might feel after him, and find him; which shows, that though it is possible for men, by a contemplation of the perfections of God, visible in the works of creation and providence, so to find God, as to know that there is one, and that there is but one God, who has made all things; and so as to be convinced of the vanity and falsehood of all other gods, and to see the folly, wickedness, and weakness of idolatrous worship; yet, at the same time, it very strongly intimates, how dim and obscure the light of nature is; since those, who have nothing else to direct them, are like persons in the dark, who "feel" and grope about after God, whom they cannot see; and after all their search and groping, there is only an "haply", a peradventure, a may be, that they find him:
The ESV reads...
(ESV) that they should seek God, in the hope that they might feel their way toward him and find him. Yet he is actually not far from each one of us,
