I have been a Christian since birth, but I am just now starting to become interested in Christian theology and why things are the way they are, so I have a few basic questions. As I understand it, Jesus had to be sent because God is perfect and we are imperfect, therefore if we were with God, God would become imperfect, so we must be made perfect by Jesus' sacrifice. So Jesus sort of takes the blame for our sins. My first question is how did the three days between death and resurrection clense Jesus of our sins? My second question is why did He have to be crucified and go through so much pain? Why would Him simply having a quick, painless death not have the same effect? My third question is that I have heard that blasphemy is the only unforgivable sin; what is blasphemy and why is it unforgivable? Thank you for any answers you can give.
