We know from the stories that are so dear to our hearts that God called Moses to lead His people out of Egypt. He called Moses to stand before Pharaoh and speak prophetic words and show the foreign leader the signs and miracles of the God of Israel. And we remember that Moses was unsure of himself, that he wasn't confident he was the man for the job.
Then, we sort of kind of remember that God gave Moses his brother, Aaron, to go with him. Aaron goes into the throne room of Pharaoh, too. Aaron carries the staff that blossoms. Aaron speaks where Moses is too insecure to speak, and it is Aaron who becomes the first priest of Israel - he becomes the prototype of those who will stand between the people and God and minister.
That would be enough to make a point - namely, that when you don't feel up to the task God has called you to, He will send help for you. He will send you someone to stand beside you and give you strength.
But...that's not all.
Because as we get into Leviticus, where the Israelites are wandering through the wilderness and trying to navigate communal life together and trying to organize an army and trying to stay in their camps and trying to settle around God's new Tabernacle and all of the people are grumbling - they are hungry, tired, scared, and unsettled just in general (as well as physically) - we see that God sent more men to help lead the people. God sent help to Moses when He sent Aaron, and then, God sends more men to help both Moses and Aaron.
Isn't that great news?
It's great news for those of us who are trying to do it all. To those of us struggling to keep so many plates spinning in the air. To those of us who keep doing the math and keep coming up short. To those of us who are tired, hungry, scared, and unsettled...and who are trying to take care of others who are tired, hungry, scared, and unsettled. To those of us overwhelmed by all the things we have to do just to keep going, let alone to do anything we might consider "glorious" for God in this world. (Side note: whatever you're doing, if you're doing it with God in your heart, it's glorious.)
God sends help. God sends helpers. God calls other men and women to come and stand beside us. He asks others to be the ones who can hold up our hands when our arms get weary and who can settle out the simple disputes that happen from time to time so that we can focus on the bigger things.
God never expected you to do this all by yourself. Never. From the very beginning, He said it: it is not good for man to be alone. And in Leviticus, we see that He still stands by it when He sends other men to help even Moses. And today, we can trust that He still believes exactly the same thing, as He sends others into our lives to help even us.
