a. Speaking the words of the king
b. Being concerned with only the interests of the king
c. Speaking only on behalf of His government
d. Maintaining connection and communication with the king, and
e. Carrying out the policies established by the king
Now although being called to be ambassadors of the king of the universe might seem overwhelming, the pressure of that responsibility is eased somewhat once we realize that all we have to be concerned with is speaking the words of our king. Keep this in mind, Jesus followed that course without exception, which is why He was so successful in His earthly ministry.
Here is an example: Then Jesus said to them "When you lift up the Son of Man, then you will know that I am He, and that I do nothing of Myself; but as My Father taught Me, I speak these things. (John 8:28)
Here is a reply that our king gave the religious leaders: 17) But Jesus answered them, "My Father has been working until now, and I have been working." 19) Then Jesus answered and said to them "Most surely, I say to you, the Son can do nothing of Himself; but what He sees the Father do; for whatever He does, the Son also does in like manner. (John 5:17,19)
Now, as ambassadors of Christ, we should be concerned only with the interest of our king. Everything we say or do should reflect His desire and purpose. Once again, our personal opinion does not matter. In the world of human diplomacy, an ambassador never shares his opinion while acting in his official capacity as the representative and voice of his government. An ambassador who strays across the line into the territory of personal opinion risks jeopardizing his nation's reputation and possibly even its security, and sets himself up for possible censure and recall.
Now, an ambassador who understands his role will simply communicate the position of his government, regardless of his private views. It is no different in the Kingdom of God. As ambassadors of our king, once again, our opinion is not important. The only opinion that matters is that of the king. Too often, as believers, we run into trouble because, having been raised in a democracy, we are too accustomed to giving our opinion with that of the king's. We end up misrepresenting Him by presenting our thoughts and ideas as His opinions, thus creating great confusion in the Church and in the world.
