(Not your normal) reflections on Exodus 7:7. 
Moses was 80 years old when he was assigned to deliver the Israelites from slavery to the Egyptians. He had been raised as a scion of the royal house of Pharaoh. He had committed murder and nearly been caught. He had run away from justice followed by certain death to a foreign land, where he got a job wandering the hills as a sheep herder. In due time, he had married and raised children. Then he returned to Egypt and there, quite reluctantly, took on the role to which he had once eagerly aspired.
From this life course, and what was to follow, we learn certain basic lessons about serving Jehovah.
Strength, insight and ability to accomplish great things do not arise within us. They are not qualities that we can will into being. Rather, we are vessels which, if fit, God can put to service. (Fit = willing and ‘essentially’ righteous.) If not fit, He can bring us into a fit state if it suits his purpose. (Ex 2:11,12; 4:10-12) The essential ingredient that we bring is only a willingness to serve him out of love. That’s it, willingness born of love is all we put on the table. Everything else we have, including our current breath, is a gift from him. The very best we can do with these gifts is to “return them” in the sense of placing them at His service. But we have the same freedom of choice as regards the willingness and the love as Adam and Eve had.
Seniors are no less fit for a life of such service than infants are. Moses held the rod Jehovah had given him aloft all night as the whole of the Israelite nation passed in front of him. Try that sometime with just an empty hand for a single hour. If by some chance you can do this, put 4-5 pounds in your hand to simulate the weight of the rod, stand up and hold it aloft through the night. Now, how do you think an 80 year old man managed to do that? The only reasonable conclusion is that Moses did not rely on his own strength to hold that rod aloft. If Jehovah had not strengthened him, he could not have done it. But Jehovah DID strengthen him.
Others with physical impairments or other obstacles can also render great levels of sacred service to Jehovah. Moses was an 80 year old man who had spent most of the last 40 years looking at the wrong end of sheep. He probably could “baaaaa” with the best of them, but he wasn’t fluent in the language of the Egyptian court. Possibly his Hebrew was rusty, too. Baaaaa! Yet Jehovah did not let that become an obstacle. Fluency of tongue was not the reason Jehovah called on Moses and he didn’t allow its lack to be a hurdle in his appointment. (Those considering others for congregational appointments take note: “fluency from the stage” is not a requirement for appointment.) Their course of action is to offer themselves willingly, prepare spiritually and wait on Jehovah to charge them with an assignment.
Is our course of action any different? Are we any less suited to serve Jehovah in a big way than an 80 year old murderer, a son of privilege who had fallen from his lofty position only to spend 40 years of his life shuffling sheep from place to place while his mother, father, brother and sister all struggled under an increasingly tyrannical and brutal slavery? Or are we perhaps better suited than he?
Think very carefully before you respond.
When Moses killed the overseer, he was an arrogant, violent man, accustomed to wealth and imposing his will on others – by force, if necessary. When Jehovah used him though, Moses was the meekest among all men.
And that is when God chose to use him.
Now, answer the question again: Am I an honorable vessel, fit for use today, or am I something else, suited only for dishonorable purposes?
