Read John 20 today.

John 20:24-29 NLT[24] One of the twelve disciples, Thomas (nicknamed the Twin), was not with the others when Jesus came. [25] They told him, “We have seen the Lord!” But he replied, “I won’t believe it unless I see the nail wounds in his hands, put my fingers into them, and place my hand into the wound in his side.” [26] Eight days later the disciples were together again, and this time Thomas was with them. The doors were locked; but suddenly, as before, Jesus was standing among them. “Peace be with you,” he said. [27] Then he said to Thomas, “Put your finger here, and look at my hands. Put your hand into the wound in my side. Don’t be faithless any longer. Believe!” [28] “My Lord and my God!” Thomas exclaimed. [29] Then Jesus told him, “You believe because you have seen me. Blessed are those who believe without seeing me.”
Thomas struggled to believe because he happened to be absent during Jesus’ first visit with the disciples after His resurrection. Have you ever had a thought that started out with, “I won’t believe it unless…”? What holds you back from fully believing?
