WoW2: Get the mission right and live with the pain.
In life, you feel pain. Some are mental, some are physical, some are self inflicted, some seemingly a gift from God. The pastor is forced to deal with pain because God needs to answer for it. While it is sometimes wise to think about the reasons for the source of pain, the example of Paul continuing his work in spite of pain must surely be a beacon of light for all of us.
"We put no stumbling block in anyone's path, so that our ministry will not be discredited. Rather, as servants of God we commend ourselves in every way: in great endurance; in troubles, hardships and distresses; in beatings, imprisonments and riots; in hardwork, sleepless nights and hunger; in purity, understanding, patience and kindness; in Holy Spirit and in sincere love; in truthful speech and in the power of God; with weapons of righteousness in the right hand and in the left; through glory and dishonor, bad report and good report; genuine, yet regarded as imposters; known, yet regarded as unknown; dying, and yet we live on; beaten, and yet not killed; sorrowful, yet always rejoicing; poor, yet making many rich; having nothing, and yet posessing everything." 2 Cor 6:3-10
