The risen Jesus is standing there in front of Thomas. The rest of the disciples are in a semi-circle, watching closely, listening to every word. You're off to the side taking it all in.
Thomas didn't make a move when Jesus invited him to "put your finger here and see my hands, and bring your hand and put it into my side." He just stood there looking into Jesus' eyes.
Then Thomas speaks to Jesus words that no other disciple has yet spoken to him. He addresses Jesus with the same words Israelites had used for centuries to address the one and only God. Thomas says very slowly: "My Lord and my God."
Everyone in that semi-circle is Jewish and knows what those words mean. They (and others) had addressed Jesus as Rabbi, Messiah, Prophet, Son of God. But the "doubting Thomas" is the first to address Jesus in the same words with which the Chosen People had addressed God.
Right before your eyes, we see Thomas look upon Jesus with the eyes of faith. Thomas recognizes that Jesus is not simply the first human being to overcome death, not simply someone sent by God, not simply special to God, not simply adopted by God. Jesus is God.
Everyone, myself included, moves their lips as they say quietly and fervently, "Yes ... Amen."
