Always, it is good to remember that the preaching work is never about us. The angels are directing the work and those that Jehovah is drawing will be drawn to the message. Being available consistently for the privilege of being used makes us more in a position to receive the blessings of being used by Jehovah and the angels. I am in an area so rural there is nowhere to use the carts, but hope to do so one day when I go visiting elsewhere.
