The scriptures of this day remind me that God is always there with us and preparing our way before we even know. Often this gospel is read at funerals as a comfort to those who survive that their loved one is cared for and at home. I can imagine an eternal home where we can all be together, to be present with all those we love and who love us. 
I too have those doubts at times as Thomas, "we do not know where you are going, so how can we know the way?" When I'm feeling unsure about the future or the next steps even, I need to remember that Jesus is the way, the truth and the life... follow me..." I often need to remember to have trust and follow, the way will be opened before me, and if not, then maybe I need to stop and wait until the way forward is clear. To have the ongoing discernment on the journey, to stop and check the way as I go - remembering who I follow, who calls me and who leads me. 

When I am answering the call with a sense of grace, I find that my heart is at peace, my faith is strengthened, and I have a knowing of the rightness of the journey.
