This is interesting . In the third paragraph you stated that
He shed his blood for the ones who believe in order to save them from hell
Your statement suggests that Jesus died for those who believe but the scriptures (John 3:16, Matthew 13:44,38) shows us that Jesus actually died for everyone. Was it possible to believe in the salvation work of Jesus Christ before Jesus Christ came? Is salvation available to those who have not yet believed?
