A South Dakota rancher and his bride received a nice Bible as a wedding gift from his grandfather. They wrote a thank you note and stowed the Bible in a closet. The grandfather asked every so often how they liked it. Eventually, they became curious, dug it out, and leafed through it. They found 66 twenty-dollar bills—one in each book. The grandfather left $1320 in monetary treasure to be discovered, but God has left inestimable eternal spiritual riches (story adapted from Kathleen Norris. Amazing Grace: A Vocabulary of Faith). Understanding the Bible takes effort (2 Timothy 2:15), but its treasures are worth the investment.
