Believing in Jesus means life, even after death.
For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord. – Romans 6:23
The verse is not speaking of physical death, but is contrasting spiritual death with eternal life. The person who does not place his or her faith in Jesus Christ will receive the wages (payment or consequences) of sin, that being a spiritual death.
