After we die, we either return to God or are separated from him for all eternity. If we do not believe in Christ or believe in him with a weak faith, we should never take it for granted that we are going to heaven. Also, even if we do not do anything evil, we'll have difficulty getting into heaven if we live an entirely self-centered life. For to live for yourself only is not to live for God at all. We must do our utmost to safeguard our soul, created by God and most precious to him!
