Newborn babies are not "men".... probably go straight to heaven if they die.
'Men' there is not speaking about adults or males, it is speaking about mankind/the human race which includes males and females of all ages.
Are you actually claiming that a newborn baby is born sinless?
LOL! You have a problem here for your beliefs based on your answer to the above.
You want to say that babies are born sinless because they are too young to do anything to get saved, so a sinless baby in your reasoning could go to heaven.
If the baby was born with sin and later died and could not have done anything to get save in your view, where does that baby go? Does God take the sinful unsaved baby?
If you say that a baby is born without sin, then at what point/age does a baby/child become sinful?
And if you claim babies/young children are sinless from birth until some point, then why/how do babies/children even get sick or die during the point that you think they are sinless?
Regarding Lazarus: I coulnd't make out your point. Are you wondering why he died again after being resurrected? If so, it is because he was a sinner.
He was a sinner because it was passed on upon him through Adam, right?
But he died paying the wage for sin, so when he was resurrected, he should not have been under the adamic sin penalty of death.
[14 Then Jesus said to them plainly: “Lazʹa·rus has died,]
[43 When he had said these things, he cried out with a loud voice: “Lazʹa·rus, come out!” 44 The man who had been dead came out with his feet and hands bound with wrappings, and his face was wrapped with a cloth. Jesus said to them: “Free him and let him go.”]
[23 For the wages sin pays is death, but the gift God gives is everlasting life by Christ Jesus our Lord.]
