Again, God doesn't send people to hell...people send themselves there, it's like if a person stole from others his whole life, only to be arrested and when asked about his crimes openly admitted to them, he obviously can expect to pay for his choices and is sentenced, but then after the verdict is delivered he whines about being sent to prison asking why can't he be set free? if that happened in the media today I think people would have little pitty on the man and think he is getting what he deserved, why not the same with God?
Actions have consequences and everything people do, and every choice will ultimately affect others. But you may wonder what if a good man lives his life helping others? gives every cent to charity and in just a super citizen but is not a believer? in God's eyes sin is sin...big sin, little sin its still sin.
For example, let's say two employees work at Wal-Mart. One steals pencils, pens, paper, food every now and them from the store. Little stuff he doesn't need but takes just for the hell of it. But the other employee is stealing things like CDs, DVDs, Cameras, Ipods every night just for the hell of it which would you think of as being the more criminal?
Truth is they are both just as guilty, the size and price of the items don't mean jack squat because it's like the bible says in 1st Samuel 16:7
"But the LORD said to Samuel, "Do not consider his appearance or his height, for I have rejected him. The LORD does not look at the things man looks at. Man looks at the outward appearance, but the LORD looks at the heart."
-1st Samuel 16:7
And in the eyes of a perfect God anything less than perfect is just that...less, it's not perfect; it's lacking in something. No man can enter heaven by his own works no matter how many he has...granted, the bible says the good deeds you do knit your clothes in heaven. But they in themselves aren't a free pass into heaven.
