In the Book of Exodus God established the priesthood though Moses. He instructs Moses to gather Aaron, his sons, Nadab, Abihu, Eleazar and Ithamar. He told Moses to make holy garments for glory and for beauty for these men.
The purpose was that they "may minister unto Me in the priests office."
A priests function and the word "minister" means to wait upon; to attend to.
The Bible says that Israel was established to be a nation of priests and kings, established, determined, and appointed so by God.
To wait upon, to serve God.
I have no problem going to God when I am need. I have no hestitation asking Him for His favor, His blessing and for answers to my requests. But to fulfil the function of ministering to Him? Everyone has needs, health issues, requests, and desires we take to Him continually. And we should. There is no One on earth who can do what He can do. But do I minister to Him?
I cannot imagine being in His place with possibly 6 billion people petitioning Him for answers to our prayers. Who ministers to Him? Who waits on Him; not waits upon Him for answers, but actually waits upon Him like a servant?
I believe we wait upon Him when we obey His words by our lifestyle, by our intercession on behalf of others, when we present Him as the only One and true God who created us to bring praise and glory to His Name. A Name describes who a person is and He has declared that He is the Great I AM. He is all in all.
We minister to Him when we just sit and thank Him for who He is; without any requests, although we usually have them, but to just take time each day and dwell upon Him and who He is, what He is to us, what He has done for us in the past and what He has promised to those who finish the race successfully.
Thank Him for the power and ability to run the race, for being available for us to praise and thank and worship. After all, He is all in all. He us our purpose, He is our life, He is our high tower and a Rock in which we can hide in these last of the last days.
He has promised that we are in the palm of His hand, and none can snatch us out of that place. Thank Him for that awesome thought!
