Do The Details Really Matter That Much,really?

It is very interesting to note that if Jesus truly died and just believing in that death guarantees paradise, then one will wonder what will happen to the likes of Hitler and his associates. They were christians and probably delieved in Jesus as the Bible has preached it. One will then ask if it is necessary to do any work of goodness, along with that'belief in Jesus' death.'

I am just asking, from what point is the blanketted believe in the death of Jesus and his saviorship start, from when he was born,when he was baptised, when he began his mission, or when. Just in case someone died before Jesus died, or according to the Bible rose up the third day (72 Hours), what happen. By the way from Friday evening to Sunday morning is not up to 48 hours, using any system. Would grace of Jesus covered those who were before him, eg, Adam, Noah, Ibrahiim, Moses, etc.
