I have pinged you to the Fruit of the Lutherian heresies.
Keep pinging. Knowing that I have a personal relationship with Jesus Christ (without having an intermediary, be it a priest or the Virgin Mary) is a great joy. Knowing that I will not have to buy indulgences to keep from spending time in purgatory means that I can use my resources to help fellow human beings, and maybe spread the Gospel of Jesus Christ to a few. Knowing that faith alone saves me provides great peace of mind, and empowers me to do Christ's work.
