Scripture says we should "always be prepared" to explain our faith, so let's consider this question:
"How can you take the Bible literally? For example, It says trees clap their hands in Isaiah 55:12."
Although Christians often say they take the Bible "literally," it would be more accurate to say we believe the Bible is God's Word and is trustworthy, unchanging, accurate and true.
God's Word contains historical narrative, poetry, proverbs, songs, parables, and instructions.
And because God speaks in ways we understand, He sometimes uses figures of speech.
It's easy to recognize which phrases are figurative, and we don't take those phrases literally.
Isaiah didn't believe trees had hands any more than Jesus meant sinners should chop theirs off (Matthew 5:30).
God divinely inspired these figures of speech to give us the most vivid, interesting, accurate understanding of His truth. His Word is the incredible true story of creation, mankind's fall, and redemption. We trust every word, but we don't take every word literally.
P.S. Despite a long-standing rumor, Christians never thought the earth was flat by taking certain verses literally. See Flat Earth Lie.
