The wages of sin is death

Meaning: If we sin we die. ("Death" here refers not to physical death but to spiritual death or eternal damnation.)

Note: wages (noun) = the result of doing something considered unwise or wrong (this is a rare, figurative use of the word "wages" which is normally the plural form of "wage", a regular payment for work) | sin (noun) = an immoral act considered to be against the law of God

Origin: The Bible (Romans 6:23): "For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord."
