So then, without scripture to reveal this God, wouldn´t his observed acts contribute to the judgement of this god ? If there have been no observable acts, and no revelation through scripture, what are you left with ?
Not really the topic here, but just because YOU have seen no observable acts does not mean others have not.
I often use the analogy of rogue waves -which were once thought to be myth -until many could see they were not.
I call such things unusual arrangements of ordinary things -some of which can not be readily reproduced.
God once did things to be seen by many when his overall plan called for it -and will again -but meanwhile he calls individuals and actually iniates their faith (not all who believe actually have faith) on a more personal level -and it is not possible for individuals to reproduce HIS acts. They are also sometimes more subtle than extremely obvious.
(some bible verses woven in here -do not have time to look up.
Faith is not actually blind. It "is the
substance of things hoped for, the
evidence of things not seen." (bold mine)
If you consider those of great faith in the bible, you'll notice they also observed God's acts.
When it is initiated, WE are mostly blind, and it increases "from faith to faith" -that is... from substance to substance and evidence to evidence.
If you eventually observe something and say "that's not supposed to be able to happen" -and don't know how it could have happened -you will have evidence of something unseen.
Such an event might also open your mind to things you once thought completely impossible.
That is not the whole story -but is similar to how it begins.
If there were no scripture, there is still the environment. The environment -including ourselves -can not reveal some particulars, but what is generally right and wrong -true and false -can be known thereby -and is indicative of that which created it.
Rom 1:19Because that which may be known of God is manifest in them; for God hath shewed
it unto them.
20For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made,
even his eternal power and Godhead; so that they are without excuse:
THE MOST IMPORTANT thing we can observe from that which was made is that universal keeping of the commandments would make the world wonderful. As many point out, they were generally not original to the bible. The first few are so as they refer to the God described in the bible specifically, but even if one has not observed evidence that God is self-aware, etc., the principles behind even those are observably correct. Our present striving against each other and fighting over different belief systems is illogical, for example, because there is one overall reality, on set of overall truths -one reference for all. That reference should not be mocked, but taken extremely seriously -not in vain.
...and who could not agree that we all definitely need a day off?
Most of humanity will not be called to the first resurrection -and they are not "doomed". They will be raised to the judgment -and judged according to their WORKS -NOT SPECIFIC BELIEFS
