Viz, that's what my father just passed away from. It's nice to know that he is finally free of shaking and in a place where he can shout and sing. He lost most of his voice 4 years ago due to a stroke at that time.
Really hard on him as he was a pastor and loved to preach AND talk with others. Had a real gift of comfort and counsel.
When he first entered the ministry, he met with a man that was in the final stages of parkinsons (back in the 60's) and prayed that he would never get it. When he did, he never complained, but I saw his faith grow ever stronger as he used it to minister to others who had it.
God never promised that we wouldn't go through difficulties... but He did promise that He will sustain us and give us strength to cope as we turn to Him.
