The Doubtful Becomes a Believer
John 20:24–29
“But Thomas, one of the twelve, called Didymus, was not with them when Jesus came. The other disciples therefore said unto him, We have seen the Lord. But he said unto them, Except I shall see in his hands the print of the nails, and put my finger into the print of the nails, and thrust my hand into his side, I will not believe. And after eight days again his disciples were within, and Thomas with them: then came Jesus, the doors being shut, and stood in the midst, and said, Peace be unto you. Then saith he to Thomas, Reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust it into my side: and be not faithless, but believing. And Thomas answered and said unto him, My Lord and my God. Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed.”
(John 20:24–29)
Introduction
Who has not heard of the unbelief of Thomas, often remembered as “Thomas the doubter”? His story has long captured attention and is often used as an emotional tool to induce guilt rather than instruction. Yet the account of Thomas provides far more than a lesson in doubt—it offers a profound biblical teaching on the nature of faith.
Thomas’ experience occurred eight days after the resurrection of Jesus Christ. By that time, the other disciples had already seen the risen Lord and reported the truth to him. Like Thomas, they too had once been discouraged and confused by the death of their Master. In every post-resurrection appearance, however, Jesus patiently instructed His disciples concerning the necessity and meaning of His suffering, death, and resurrection.
The resurrection of Christ brought victory over mankind’s greatest enemy—death—and transformed despair into confidence and joy. The Apostle Paul later affirmed that many of Christ’s appearances were unrecorded, yet those preserved in Scripture exist for our instruction. Thomas’ encounter with the risen Christ provides an especially significant lesson about faith for believers today.
The Reason for Thomas’ Unbelief
John records that Thomas was not present when Jesus first appeared to the assembled disciples following the resurrection. His absence cost him the immediate encouragement and assurance experienced by the others. Because Thomas did not witness Christ’s first appearance, he remained trapped in the discouragement produced by the crucifixion.
Scripture consistently emphasizes the necessity of assembling with the people of God. Hebrews 10:25 declares:
“Not forsaking our congregation, as is the manner of some, but admonishing one another; and all the more so, as you see that day approaching.”
Likewise, Jesus Himself promised His presence among believers when they gather together (Matthew 18:20). Thomas’ isolation from the fellowship contributed directly to his prolonged doubt.
Thomas also revealed that his faith depended entirely upon physical evidence. He insisted upon seeing and touching the wounds of Christ before he would believe. His demand for tangible proof reduced divine revelation to human limitations and exposed an egotistical self-dependence in his declaration:
“Except I shall see… and put my finger… and thrust my hand… I will not believe.”
Despite knowing Jesus’ repeated promises about His resurrection, and despite the testimony of ten fellow disciples—sufficient evidence under Jewish law—Thomas rejected their witness and limited truth to personal observation alone.
The Patience of the Lord Jesus Christ
Eight days later, Jesus appeared again, this time with Thomas present. During that week, Thomas had heard continual testimony from the disciples and the women who affirmed Christ’s resurrection. When Jesus appeared, He showed full knowledge of Thomas’ doubts and addressed him personally.
Rather than rebuking Thomas harshly, Christ displayed remarkable patience and compassion. He invited Thomas to examine the evidence he demanded and encouraged him with the gracious command:
“…be not faithless, but believing.”
The same Jesus who had been crucified and buried now stood before Thomas, alive, victorious, and offering undeniable proof of His resurrection.
Thomas’ Declaration of Faith
Confronted with the risen Christ, Thomas made one of the clearest confessions of Christ’s deity found in Scripture:
“My Lord and my God.”
This declaration affirmed both the absolute lordship and the divine nature of Jesus Christ. Thomas acknowledged Christ’s authority, rooted in His position as the Son of God, and recognized that redemption had been accomplished through His blood.
Jesus’ resurrection confirmed the necessity of His death and resurrection for the remission of sins, as recorded in Luke 24:44–47. Through faith, Thomas personally claimed Christ as his Lord and his God, ending all remaining doubt.
As John writes:
“But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name” (John 1:12).
Through faith in the risen Christ, Thomas became a child of God, fully assured of salvation.
The Promise to Future Believers
Although Thomas believed after seeing, Jesus confirmed his faith while extending a profound promise to those who would believe without direct physical sight:
“Blessed are they that have not seen, and yet have believed.”
This promised blessing applies to all believers who come to faith after Christ’s ascension—those who must trust the testimony of Scripture rather than personal sight. Faith that rests upon God’s revealed truth, rather than human observation, receives special blessing.
Thomas’ doubt sprang from reliance upon carnal reasoning, but faith brought surrender and confidence. Seeing the risen Christ did not save Thomas—belief did. Faith, not sight, remains God’s appointed means of salvation.
Conclusion
Natural man relies upon physical evidence and human reasoning to confirm truth, but such methods fail completely when applied to spiritual realities. God is infinite, eternal, and beyond the limitations of finite human understanding. When man insists upon tangible proof, his soul is left hopeless and unsatisfied.
Thomas’ experience shows that genuine hope and assurance come only through faith apart from material evidence. Scripture declares:
“Now faith is the substance of things hoped for… But without faith, it is impossible to please God” (Hebrews 11:1, 6).
Peter further affirms that faith without sight produces joy that is “unspeakable and full of glory” (1 Peter 1:8).
Doubt arises when faith is replaced with dependence on what can be seen. Bold confidence and lasting hope are built upon complete trust in the unprovable yet absolute reality of the all-powerful God.
