Okay, I am glad you chose Acts 17, so I will attempt to show you where and how you're wrong, imo...
First, let's set the backdrop of what type of environment Paul was stepping into at Athens...I will use the YLT....
16 and Paul waiting for them in Athens, his spirit was stirred in him, beholding the city wholly given to idolatry,
This is the type of environment one should expect when stuck in paganism. Shoot, look at what happened when Moses was on Mount Sinai. They made a golden calf to worship. People who know not God will create a god to worship. Look at all the OT gods that were mentioned. Even the native american indian believed in a 'happy hunting ground' for them when they died, and they left the hearts of the animals they killed so that their spirits would roam the forest.
21 and all Athenians, and the strangers sojourning, for nothing else were at leisure but to say something, and to hear some newer thing.
All they were were a bunch of busybodies and seeking worldly knowledge. If someone would have came along and was promoting Islam, they would have wanted to hear about it. Same as with mormonism, buddhism, &c.
23 for passing through and contemplating your objects of worship, I found also an erection on which had been inscribed: To God -- unknown; whom, therefore -- not knowing -- ye do worship, this One I announce to you.
Now, they had so may gods they worshipped and even had a altar dedicated unto the 'unknown god'. They had no idea, no clue, into who to worship. This is why God sent Paul there...He had sheep there to bring into the fold.
24 God, who did make the world, and all things in it, this One, of heaven and of earth being Lord, in temples made with hands doth not dwell, 25 neither by the hands of men is He served -- needing anything, He giving to all life, and breath, and all things;
Here Paul is telling them that God doesn't dwell in temples made with hands. He is rebuking them for their gods they have strung all over the place.
30 the times, indeed, therefore, of the ignorance God having overlooked, doth now command all men everywhere to reform, 31 because He did set a day in which He is about to judge the world in righteousness, by a man whom He did ordain, having given assurance to all, having raised him out of the dead.'
Why did God command all men everywhere to repent/reform? Because of the day when Christ will judge the world in righteousness. Now, God commanded all of Isarel to keep the Law, and if they broke it, they died. God knew full well they couldn't, commanded them to keep it, and punished them accordingly. We are even told to "be ye holy even as I am holy", yet can we meet those standards? Absolutely not. The only way is through Christ.
Now, here is why God sent Paul to Athens....
32 And having heard of a rising again of the dead, some, indeed, were mocking, but others said, `We will hear thee again concerning this; 33 and so Paul went forth from the midst of them, 34 and certain men having cleaved to him, did believe, among whom [is] also Dionysius the Areopagite, and a woman, by name Damaris, and others with them.
You can see that the gospel will never go 'response-less', because it will alway elicit a repsonse, whether in a positive or negative manner. Some mocked Paul and some desired to hear more. That is the way the gospel works. Some receive it, some reject it.
