After his resurrection, Jesus appeared to his apostles, but Thomas wasn’t among them. So when they told him about it he didn’t believe them saying that he will only believe it if he gets to touch Jesus’s wounds.
So Jesus appears before him and makes him touch his wounds to show him that he has indeed returned from the dead. The painting is about that.
