I consider my challenge to be my self-doubt. I find it difficult to believe that I have the skills to overcome, tackle or succeed at the task I have been assigned. I consider myself a participator: someone who can be given an assignment and then help to carry it out.
My "tonic" to cure this is to clean my ears and quietly listen for the voice of the Holy Spirit and to hear the suggestions, observe visual cues, study the subject more intensely.
It is difficult to name one person. Many people have encouraged, prayed and supported me in my efforts to be a vehicle to spread the Good News. For their words, support and encouragement, I am greatful.
