John Bible Study, Day 38: Thomas Believes

Today’s passage: John 20:19–31

Focus verse: Thomas said to him, “My Lord and my God!” (John 20:28)

The Bible writes that faith is having confidence in the things we hope for and assurance in what we don’t see (Hebrews 11:1). Today this definition of faith applies to us.

We cannot see Jesus, so we must accept his resurrection and the salvation that he provides through faith. We have confidence and assurance that he overcame death to save us.

The disciples and Jesus’s other followers have it better than we do. Some of them see the empty tomb and eventually all of them meet the resurrected Jesus. It doesn’t take so much faith to believe what their eyes perceive. John, “the other disciple,” sees and believes (John 20:8).

We can assume that Mary and Peter also believe once they see the evidence of Jesus’s empty tomb (John 20:1–2 and 6–7). The rest of the disciples believe when they see him (John 20:20)—or at least everyone except Thomas.

Though Matthew, Mark, and Luke only mention Thomas once, John tells us more about him than the rest of the Bible combined. He shares three accounts about Thomas. 

The first story is Jesus telling his disciples what to expect and encouraging them to believe. He talks of preparing a place for them in heaven and coming back to get them so they can hang out with him forever. Then Jesus adds, “You know the way.”

This confuses Thomas. He wants clarification.

Jesus responds with what has become a familiar verse. “I am the way, the truth, and the life. No one comes to the Father except through me” (John 14:6).

The second story is what Thomas is most known for. This is where we get the phrase doubting Thomas. When Jesus rises from the dead and sees his disciples for the first time, Thomas is absent.

He doesn’t believe the disciples when they insist that Jesus is alive—again. Thomas does the reasonable thing and demands proof.

In the third story, the disciples, including Thomas, hide in a locked room. Jesus materializes in their midst. He shows Thomas the nail scars in his hand and invites him to examine his side, pierced by the soldier’s spear. “Stop doubting,” Jesus says, “and believe.”

At last, Thomas does. “My Lord and my God!” Thomas now believes. He is no longer doubting Thomas but believing Thomas.

Though doubt characterizes him for a time, belief is where he ends up. He finishes strong. May we do likewise. May we have a firm belief in Jesus and who he is.

Jesus blesses Thomas because he sees and believes. We’re more blessed because we haven’t seen and still believe.
