You asked, so I'll tell you.
We believe that 2000 years ago God sent his son to earth through a virgin named Mary. His name was Jesus. Jesus brought the truth to all people by telling them of God's love and his ability to forgive them of their sins. Jesus was persecuted for his belief and eventually was sentenced to death. He was beaten and spit on. They took a whip with pieces of bone tied into the ends and whipped his back until it was nothing but mangled flesh. Then they placed a crown of long thorns on his head and pressed it down upon his head until he bled. After all of this they made him carry his own cross of heavy wood up to a hill called Mount Calvary. There they laid him down upon the cross and drove nails into his hands and feet. The nails were about the size of railroad stakes. Then they stuck the cross into the ground letting his full weight hang off of the stakes. There they cursed his name and spat at him some more. After he hung there for a while one of the soldiers came up and ran him through the side with a spear. There he died. He was buried in a tomb and laid there for 3 days. When he died he went to hell and obtained the keys to life and death. He did this so that we, who are born into sin can be forgiven. He took the blame and punishment so we don't have to. His blood was shed so that every man would have a chance at life. Only by forgiveness of our sins are we able to go to Heaven. Are there some Christians who lie? Are there some who are hypocrites? Yes, being a Christian doesn't make us better or different from anyone else. Except for the fact that we are aware of our sins and have asked for forgiveness. I was born a sinner but God has forgiven me through the blood of Jesus Christ. If you think that Christianity is all false just because of what you've seen some TV preacher do or someone who claims to be a Christian in the news do, then you're missing something. You're placing your faith in men. Like I said, men fail. Once you become a Christian doesn't mean you're perfect. There are people out there that will claim to be Christian, but do not live as a Christian should. Why? Because they're human. No, put you're faith in God. He is the one who will not fail you.
After 3 days Jesus rose from the grave after having defeated death and the grave. There he commanded his disciples to go into all the world and preach the gospel. Then he descended into Heaven on a cloud of glory.
Sound far fetched? If I heard it likes this, over a message board, I think it would to me too. Yet, I have seen the evidence of this like I said in my previous posts. I have seen it and felt it. Just like nmaino said, it is by faith that I believe what I believe.
