The answer is: The nail marks in Jesus' hands

John 20:24-25 - Thomas did not believe on the testimony of the other ten disciples.

Thomas, often affectionately dubbed “Doubting Thomas,” gave us a glimpse into one of the most human reactions to miraculous claims. In John 20:24-25, his insistence on seeing the nail marks in Jesus’ hands speaks volumes — he wanted tangible proof that was undeniable. This instinct for verification can resonate with many of us who lean towards reason and require solid evidence before accepting seemingly outrageous claims.

Interestingly, Thomas is also known for a bold declaration when Lazarus was resurrected — he believed faith compelled him to go face adversity despite potential danger. So, while Thomas' demand for proof may appear as doubt, it also surfaces his heart’s passion for authenticity and loyalty.

This moment in scripture draws a fine line connecting faith and reason. Despite doubts, it’s through Thomas’ skepticism that we glean deeper faith — once he does see and touch the scars, his proclamation “My Lord and my God!” transcends mere belief.

Did you know that the name "Thomas" means "twin" in Aramaic? He’s seen as a symbol for all of us grappling with doubt and revelation. And in a wonderful full circle of grace, Thomas ultimately travels, spreading the message, potentially reaching as far as India. Isn’t it fascinating how his journey highlights the transformative power of faith, blooming through wrestles of uncertainty?
