Thomas—one of the twelve disciples—was not with the other disciples when the resurrected Christ appeared to them. They told him, "We have seen the Lord!"
Thomas replied, "Unless I see the nail marks in his hands and put my hand into his side, I will not believe."
For seven days Thomas lived in this doubt without the evidence he was asking for, then Jesus showed up literally in the flesh. Thomas was able to see and touch Jesus, and he responded with faith saying, "My Lord and my God!"
Then Jesus spoke those precious words, "You believed because you have seen me. Blessed are those who have not seen me but still have believed."
Friends, be encouraged. Jesus is talking about us!
None of us heard Jesus teach at the Sermon on the Mount. None of us saw Him heal the sick or raise the dead or turn water into wine. We have all believe without ever seeing the resurrected Christ.
And for those of us who might require a little more evidence, Jesus is there to offer it, just like He did for Thomas.
