He preaches the Miracles Jesus can do in your life when you give your life to him when you repent of your sins with a sincere heart, he gives hopeless people hope because those are the promises of Jesus Christ.
He does not promise people they are going to go home be instantly cured, win the lotto, become famous, he preaches what prayer and Jesus and reading your Bible will do for your soul your eternal salvation.
Sometimes Jesus is more concerned about our Spiritual Healing first before our Physical Healing, none the less he hears all prayers from sincere people.
Keep it up sister! You got the demons, scoffers, and pharisees rattled now... :)
