Ink
Ink turns up only four times in Scripture, and each time it sits beside something more lasting. Baruch tells the officials, “I wrote them with ink in the book,” taking down Jeremiah’s words as they were spoken. John, near the end of his life, says he would rather not use paper and ink but come and speak face to face. Paul goes further and calls the believers a letter written “not with ink, but with the Spirit of the living God.” Read 2 Corinthians 3:3 first: it shows that the message mattered more than the writing materials.
