Ministry.

“But Moses said to him, ‘Are you jealous for my sake? Would that all the Lord’s people were prophets, that the Lord would put his Spirit on them!’” (Numbers 11:29, ESV)
From what we see in the book of Numbers, the Israelites in the desert complained constantly. Here we see a series of such complaints made by a group of Israelites concerning the food. Perhaps they were bored. Perhaps they were not prepared to wage holy war. Maybe they had gotten used to the slow pace of life in the wilderness, or had gotten comfortable staying in the same place. They complained to Moses so often that he complained to the Lord that he was weary of the people and did not know how to handle them. So the Lord provided him with help from the elders of the tribes. He even anointed 2 additional men to prophesy, that is to preach the Word of God.
This passage should show us that the life of a Pastor is not easy. Leading a group of people who are selfish, immature, and stubborn is as difficult for any one of us as it was for Moses. And the Church is composed of such people. Our leaders need our help. We must support them emotionally and financially and with our prayers but also with our own efforts. We are all called to spread the gospel, it is not the sole responsibility of the Pastor or even those who are in elected positions of leadership and service. As God anointed Eldad and Medad, He has anointed every believer to preach the Gospel, Therfore He can choose any of us who are His servants to do whatever service He commands.
