Book of Life
The Bible is very clear, before God's Tribunal all men will be judged according to their actions in life. The only way to escape condemnation is receiving Jesus as Savior. That way your name will be written in the book of life. To one day be in Heaven it is essential to be written into the book of life. If not we will be judged according to our actions, even our best actions have stains in the eyes of God, who reads our hearts. We add less than noble feelings to our actions sometimes, for example, the wish to pretend, pride. In the meantime we should not hesitate to go to God for His forgiveness.
