Evangelicals believe in two forms of divine revelation: general revelation through nature, and special revelation contained in scripture. General revelation reveals God as creator, while special revelation reveals God as redeemer and contains the only authoritative teachings about salvation. Both forms of revelation are necessary. While scripture is infallible, human interpretations can be fallible, so interpretations of both revelation sources should prioritize the understanding with more certainty, such as general revelation clarifying scripture where human understanding was previously in error.
