We have the power of knowing our past mistakes are forgiven. We have power of knowing that our sins of not witnessing are erased. We have power of knowing Christ will continue to forgive us, should we fail again. This power is the right tool for the job. We have power to witness because we believe in Christ and we know we are forgiven.
Faith comes with power, enough power to get the job done.
We have power, in addition, knowing what this life is all about. Yes, we do understand what life is about. We know it is a temporary existence here, for a short time, in which we are to serve our Lord. That is what life is about. Then, the life to come follows this life, incredibly unpleasant and painful for some, but extremely joyful and a delight for others.
