Final answer:
The correct answer is option 2) Interpreting the Psalms in light of the New Testament.
Step-by-step explanation:
According to Longman's approach, when reading the Psalms in a Christian context, one should avoid interpreting the Psalms solely through the lens of the New Testament, without considering their original historical and cultural context. Longman emphasizes the importance of understanding the Psalms as they were first understood in their Hebrew context before considering their later Christian interpretations.
This does not mean that one should avoid interpreting the Psalms in light of the New Testament altogether, but rather, that the New Testament should not be the only lens through which the Psalms are viewed. This ensures a more nuanced and comprehensive understanding, which respects the Psalms' original intent and meaning while also exploring their significance within Christian theology.
