If you will notice, the Bible describes many times where God wants to directly use someone or to directly speak to someone yet the person (or group of people) want someone else between them and God, or them and the task. You can see an early example of this in Exodus 4 where God wants Moses to speak to Pharaoh yet Moses begs off because he thinks he won’t be good enough for the task. So instead of what God really wants, Moses to speak directly to Pharaoh, we end up with a man-in-the-middle: Moses speaks to Aaron who speaks to Pharaoh. Notice how Moses resists God:
"Exo 4:10 And Moses said unto the LORD, O my Lord, I am not eloquent, neither heretofore, nor since thou hast spoken unto thy servant: but I am slow of speech, and of a slow tongue.
11 And the LORD said unto him, Who hath made man's mouth? or who maketh the dumb, or deaf, or the seeing, or the blind? have not I the LORD?
12 Now therefore go, and I will be with thy mouth, and teach thee what thou shalt say.
13 And he said, O my Lord, send, I pray thee, by the hand of him whom thou wilt send.
14 And the anger of the LORD was kindled against Moses, and he said, Is not Aaron the Levite thy brother? I know that he can speak well. And also, behold, he cometh forth to meet thee: and when he seeth thee, he will be glad in his heart.
15 And thou shalt speak unto him, and put words in his mouth: and I will be with thy mouth, and with his mouth, and will teach you what ye shall do.
16 And he shall be thy spokesman unto the people: and he shall be, even he shall be to thee instead of a mouth, and thou shalt be to him instead of God."
Another - - and sadder - - example is in Exodus 20 when God would have spoken directly to the people but they want Moses to hear what God has to say and come back and tell them. Instead of the people hearing directly from God they make Moses the man-in-the-middle.
"Exo 20:18 And all the people saw the thunderings, and the lightnings, and the noise of the trumpet, and the mountain smoking: and when the people saw it, they removed, and stood afar off.
19 And they said unto Moses, Speak thou with us, and we will hear: but let not God speak with us, lest we die."
This is what we tend to do in the Church; instead of listening to God ourselves - - through reading the Bible or prayer - - we put a man-in-the-middle. We depend on the priest or pastor or rabbi, or a certain denomination or sect. It seems easier to let someone else think for you than to think for yourself. Other people are important to listen to - - and we should listen to others - - but we should not depend on others to be the-man-in-the-middle between us and God.
