Read John 20:19-31 with your family.
Thomas had doubts. He was like most followers of Jesus throughout 2000 years of history. Doubts is not the opposite of faith. Doubts just means you have questions, and questions help us grow our faith. If everyone had perfect faith, we wouldn’t have any conversations about faith and we would never know if someone has misunderstandings.
Doubts are a good thing.
Talk about some of your doubts with your family. Thomas still believed in Jesus even though he had a hard time understanding that Jesus came back from the dead. We can all believe in Jesus and still have questions.
