It is a great honor to represent God in the preaching of the gospel, whether to the world or to the church. However, there is an important principle here, that is, if one is going to do it, he had better be appointed to do it.
God is organized in what He does. Did He not create a human body that is organized? The human body is a type of His church, and in both, all direction comes from the Head. Does the hand take over and do the job of the eyes? Does the nose take over and do the job of the ear? No. The part only does the job that it is appointed by God to do.
And so it is in the church of God. God expects those whom He has appointed to perform a certain responsibility to do it. We bear that burden. How many times does the Old Testament contain the phrase "the burden of the Lord"? "The burden of the Lord" is the responsibility God gave to the prophets, and it is a burden in a number of ways. If a person is going to be preaching the gospel), he had better be appointed to do it and worthy to represent the One who appointed him—God the Father.
