The numbers of unbeliever's who have tried to shove the doctrine of zero punishment from God down my throat, would fill a stadium. The unbeliever's tell me how God is "love" and won't punish anyone for anything. I immediately tell them that they must not love their children because if they "loved" them, they would NEVER punish them. They would sit back and allow their child to be run over by a car, allow them to do as they please and allow them to disobey wantonly with no punishment whatsoever. They find that perposterous. Why, they would never stand back and allow their child to sass them, disobey them nor get hit by a car! Yet that's the lie they tell themselves regarding God even though His word tells them quite differently.
In the book of Romans we find a great passage that tells us that eventually God turns them over and no longer pursuits them. In the Romans passage we learn that God finally gives up on their hardened heart and allows them to sink into the pit of sin if that is what they choose:
"For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who suppress the truth in unrighteousness, because what may be known about God is manifest in them, for God has shown it to them. For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse, because although they knew God, they did not glorify Him as God, nor were thankful, but became futile in their thoughts, and their foolish hearts hearts were darkened. Professing to be wise, they became fools, and changed the glory of the incorruptible God into an image made like corruptible man - and birds and four footed animals and creeping things." - Romans 1:18 - 23
First off, we see that God does have wrath. The lie that says that God is only love is not of God, not of scripture and not sound doctrine. God's wrath is righteous but, it nonetheless is real. The scripture tells us that that "wrath" is revealed from "heaven" against ALL men who are ungodly or unrighteous. Certain people talk about "equality", God pours out His wrath equally and fairly to ALL.
Secondly, God has standards. This nonsense about God accepting anyone is absurd and contrary to what scripture says. Yes, God CAN accept anyone but, He will not accept those who openly and consistently flaunt and ignore his law. Other human beings may lift you up as "great" but God's law and standard is really all that matters.
Thirdly, there are those who claim that they won't believe nor see until there is "proof" that they can examine. In this passage as in many places in scripture, we see that there is "proof" yet, many ignore it or lie and claim that it doesn't exist. For these nay-sayers there is one last sentence which seals their fate: "so that they are without excuse". They can make all sorts of claims that the "proof" didn't exist or that they somehow missed it yet God says that they are without excuse.
Last but not least, we see that not only is there "proof" of God's existence but that "proof" is "clearly seen". You don't have to have a degree, you don't have to be a "scientist" and you don't have to be famous or wealthy to "clearly see" the proof that is literally everywhere. Guess what? You cannot claim that you weren't "educated" enough either!
