As I consider this very wise advise, I cannot help but think about how well this advise fits with Jesus' commandments in Matthew 22:
34When the Pharisees heard that he had silenced the Sadducees, they gathered together, 35and one of them, a lawyer, asked him a question to test him. 36“Teacher, which commandment in the law is the greatest?” 37He said to him, “’You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.’ 38This is the greatest and first commandment. 39And a second is like it: ‘You shall love your neighbor as yourself.’ 40On these two commandments hang all the law and the prophets.
When you think of it in light of the commandments in Matthew, this advice easily applies to all church leaders clergy and laity. If you love the Lord with all your heart, and with all your soul, and with all your mind, you are going to work as hard as you can when doing His work. The command to love your neighbor is explicit; no interpretation is required. As for ALWAYS telling the truth, I think both of Jesus' commands in these verses apply. If you love your neighbor, whether they are fellow church leaders, church members, or strangers, you are not going to lie about them, and I think the same goes for loving God. It is important to remember that the business of the church is God's business, and those who have accepted a call to do God's business have a huge responsibility. Part of that responsibility is always telling the truth. As church leaders, we cannot run from the truth because the lie is prettier, safer, or easier for the congregation to handle. If a church leader makes a decision, and is unable to truthfully support that decision to anyone who asks, he or she probably made the wrong decision. In ministry, integrity is the bottom line.
