1 Timothy 3:1: The saying is sure: whoever aspires to the office of bishop desires a noble task.
Just how much are you willing to do fro and with God? He has chosen each of us to do something for him, whether it be to just say hello to a person who is lost or to do everything in our power to save someone from a terrible thing...
But he does not just require physical things of us. He chose us because of our spiritual selves, the part which can encourage others in ways which go beyond the physical capabilities.
Just being and encouragement for someone at the right time can speak louder than anything we may be able to do for them physically!
