However, I do know from the Bible that worldly fame can't take anyone to heaven.
The only one who can save is Jesus Christ. By faith in Him you can be saved, guaranteeing you a place in heaven for all eternity, regardless of your popularity, talent, or wealth.
Did Carrie Fisher ever place her faith for salvation in Jesus Christ and Him alone? Only she and God know that. The only thing that matters to her now is her relationship with Jesus Christ.
This is what the Bible says about how to be saved:
Being world-famous doesn't save anyone from Hell. Having a fortune in worldly wealth doesn't purchase a place in heaven.
God is not impressed with worldly fame, or great riches or professional talent.
God sent His only begotten Son Jesus to die on the cross to pay for Carrie Fisher's sins. God offered her the free gift of eternal life, if only she would believe on Jesus Christ and call out to Him for salvation. God gave Carrie Fisher 60 years to accept the free gift of eternal life.
Did she ever receive Jesus as her personal Saviour? If not, it is eternally too late for her.
But it is not yet too late for you. Only Jesus Saves!
