Perhaps an unlikely model for us can be, of all people, the disciple Thomas. Thomas doubted, but yet he came back and stayed in the room with the disciples.  As Christians, we too are free to doubt.  God has created us with a mind to think and act freely.  God can handle our tough questions.  God can handle our moments of desperation, and certainly God can survive our doubt.  God, despite often our own acknowledgment, is there in our times of questioning, as well as our moments of great faith.  There is a saying that reads: "I respect faith, but doubt will get you an education."  As Christians we do not have to feel guilty that we sometimes question the things of God. God is there. God understands. But faith too, has an important role. We need to hold on to the example of Thomas when we doubt ourselves and our faith. Thomas was open and honest about it, and most importantly he stayed with the group of believers, despite the despair of this own thinking. We too, in times of frustration, in times of working things out, need to hold on to our community of faith, our church.  

 (From Pastor Randy's Sermon 4/7/2013)

From Pamela:  I think doubt is a universally shared human experience.  Everybody has moments when what we believe to be true is not validated by information or perceptions that moment.  Our beliefs and opinions benefit from regular affirmation, even if proof is not possible.  

You probably have heard that "the opposite of faith is not doubt, but, rather, indifference".  Indifference terminates the conversation (or the relationship).  The doubter still has a partially open mind that leans toward the matter at hand, waiting to learn more.  In many ways, doubt invites civil presence, and sometimes even civil conversation.  

So, when we "doubt" matters of God, in many ways it is an invitation to see what more (or what else) God is revealing to us.
