William Sangster visited a young girl in the hospital who was going blind. “God is going to take my sight away,” she told the pastor.

After a long pause, Sangster said, “Don’t let Him, Jessie. Give it to Him. Try to pray this prayer: ‘Father, if for any reason I must lose my sight, help me to give it to you.’”

When Jessie returned to church she had a guide dog with her. The dog used to sleep during the first 20 minutes of the sermon and then wake up and howl. When it saw that its howling did not silence the preacher, it went back to sleep!
