When Thomas said that he would not believe in the Lord's resurrection unless he could see and touch the wounds of Jesus, he was only asking to have that which the other disciples had already received. Not content to follow blindly, he wanted to really know and to be sure of this miracle, this risen Messiah. Doubt is not the absence of faith, indeed it is very much a part of our faith journey. By asking questions, by examining what we believe and why, our faith is ever strengthened and our ability to act as God's own in the world is strengthened, too.
The teens who are leading the campaign against gun violence in our schools know that these horrific killings are but a symptom of a greater evil, and are asking us to help. We should not doubt their dedication, but support them in bringing positive change to our society. Thomas saw and believed; let us do the same.
