Acts 9:5-9 “Who are you, Lord?” Saul asked.“I am Jesus, whom you are persecuting,” he replied. “Now get up and go into the city, and you will be told what you must do.” The men traveling with Saul stood there speechless; they heard the sound but did not see anyone. Saul got up from the ground, but when he opened his eyes he could see nothing. So they led him by the hand into Damascus. For three days he was blind, and did not eat or drink anything. 

Sometimes the Lord must take everything from us, including our health, so that we will focus only on Him.
