At Saul’s conversion, he was struck blind. For the next three days he didn’t eat or drink anything. After his sight was restored, he ate food and regained strength and began proclaiming Jesus as the Son of God.
A little time later, we find him growing in strength and in his ability to prove that Jesus was the Messiah.
Sometimes Good has to bring us low before building is up again. If you are in a low spot, don’t lose hope. God can give you new strength to help you serve him.
