I would encourage you by saying that the task before you, however monumental it may seem in your eyes, is not too big for God. I would go even further and assert that you have been uniquely prepared to take on this new leadership responsibility, whatever it is. I would tell you that your history, your education (formal or informal), and your experience are all coming together in this moment to enable you to accomplish what is being asked of you. You were made for this moment. You are on this earth, in this moment, in your community, to be a voice, a beacon, a light for such a time as this.
