Well it's ironic that you take Matthew 25 as literal confimation of your sadistic concept of eternal punishment but then don't take it literal when it comes to the idea of salvation by grace alone apart from works. The whole context of Matthew 25 is the judgement of people who think they are righteous before God. It's not a contrast between immoral God haters and Christians.
Look at verse 30...28 “‘So take the bag of gold from him and give it to the one who has ten bags. 29 For whoever has will be given more, and they will have an abundance. Whoever does not have, even what they have will be taken from them. 30 And throw that worthless servant outside, into the darkness, where there will be weeping and gnashing of teeth.’
This is a servant of the Master who is thrown into darkness where there is weeping and gnashing of teeth. It's not an immopral person or a person who denies God. It's the person who is suppodesdly a servant of God but produces no fruit. Same as those on the left who in verse 44 as "when did we see you lord and not..." The people on the left are addressing Jesus as Lord, but still ending up where there is weeping and gnashing of teeth.
My point is
@Lisa , if you want to take the parables of Matthew 25 literally you better start feeding the poor, clothing the naked and visiting those in prison, and you better have a return on the Lord's investment in you (i.e. produce fruit), or you too are going to burn in hell!
