Preach at all time, use words if necessary. In other words, your life is speaking to people. Every one of us has a ministry. Yours might not be standing in a pulpit to preach. Your pulpit is your life. You may not be able to preach but at least you can be friendly, kind and offer words of encouragement.
Not many people are reading the bible these days, but many are reading our lives. We are ambassadors of Christ. (2 Cor. 5:20). We need to ask ourselves am I representing God the best I should? We are preaching every day with our lives. We are preaching to every one we come into contact with. What message are we sending out?
