Service and Truth
First, we must serve God in truth, you do that by living and serving consistent with His word. Jesus came to do the will of his Father and we must do the same. Jesus said that we cannot serve two masters because we will either hate the one and love the other or we will be devoted to the one and despise the other. We cannot serve both God and our desires our passions, or anything else. Deacons are servants of truth, for the truth!
