This is a spiritual death or the second death, "And death and Hell were cast into the lake of fire. This is the second death". Revelation 20:14

"That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised Him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness and with the mouth confession is made unto salvation". Romans 10:9-10
