I'm a firm believer that the afterlife is what we make it. I want to meet God, Jesus, my family members and hopefully finally shake Elvis's hand. I want to ride a cloud with my own wings. I think that some people are not going to believe or ask for forgiveness, so that won't be in heaven. I'm a Christian who believes in Jesus wholehearted. I also believe that Jesus came as more than one person and walked as many because God is the greatest teacher of all. He knows what works for one group will not work for another.
Jesus explained if a man wants to feast to honor God or famine it's good as long as it's to praise God. ("The means justify the end") I don't believe that damnation is forever but more a series of your life replayed until you see the right way. I think murder is forgivable by God but people aren't capable of that kind of understanding.
I'm not sure if this is right but this is how I understand the Holy Spirit. The Father is God, the son is Jesus and the Holy Spirit is God within us. So I think it's a tough call because my first reaction is no forgiveness for blasphemy but what if a man loses everything like Job but in weakness from the hurt screams God doesn't exist, can a loving God not understand. I think all things are forgivable and beyond the comprehension of mankind. :) Thanks for listening!!
