God is perfect. He does not want to send people to Hell, He just cannot look upon sin. That is why there is a hell. Jesus died to forgive us (regardless of your opinion on this matter au1929, that's the subject of this discussion; if you don't want to hear of Jesus' sacrifice, then you shouldn't be in this thread). That doesn't mean that we're automatically assured of heaven. Just because I give someone a key to a door does not mean that he or she are going to use that key to open the door. That person may just throw the key away and not go through the door at all. Unfortunately, that's what many people are doing to Jesus.
From a Biblical perspective (NIV) (certain people might want to ignore this, especially if they are extremely prejudiced against the Bible):
Romans 6:23a wrote:For the wages of sin is death...
Mankind may look on some sins being worse than others, but God does not look at sin that way. You commit one sin, you are going to Hell. It's that simple. However, the verse continues to say this:
Romans 6:23b wrote:...but the gift of God is eternal life in* Christ Jesus our Lord.
* or through
If you accept Jesus, then you are guarenteed to go to heaven. That said, one can't simply be baptized and live a sinful life expecting to go to heaven on a free ride. One must continually work to practice the life of a Christian at all times.
