Almost everyone knows what a car looks like, or a computer, or a VCR. But it's one thing to recognize it and another to have a practical working knowledge of it. Likewise, many people have been around Christianity of a long time. They read Christian books, listen to Christian radio, and even keep company with Christian friends. But if you ask them of they have a practical working knowledge of Christianity, it's a different story. Do they know what it takes to be in right standing with God? What exactly does it take to receive forgiveness from God? What does it take to be a Christian? This message walks through the core of Christianity and gives everyone within earshot a "practical working understanding."
