People like to earn money and things. Most parents teach the kids to work hard. I believe this. We need to work hard but we can not earn salvation.
The Church of Jesus Christ and Latter-day Saints believe this. Salvation comes by works. All people will spend eternity on some level of a multistory heaven. The level will be determined by the scope of each person's good work.
The Bible teaches this. Salvation is a free gift provided by the grace (unmerited love) of God for all who believe and accept His plan.
