Read: Numbers 18-20
Marked: Numbers 18:8, And the LORD spoke to Aaron: “Here, I Myself have also given you charge of My heave offerings, all the holy gifts of the children of Israel; I have given them as a portion to you and your sons, as an ordinance forever.
We don’t serve God for gain, but we do receive gifts from God as a result. Aaron and his sons were tasked with the work related to the sanctuary, but would bear the iniquity associated with the priesthood (V1). This gives a sense of responsibility and accountability.
As the priesthood of all believers Christians are first to represent God to the world. This isn’t easy, but it is our responsibility. Many will question what we do or why we do what we do, even within the church. But we are accountable only to God.
In return God gave them what was His. They received the best of the best of the offerings (V9, 11, 12, 29). This was their inheritance from God. They had no other inheritance in the world. God, and God alone, was their portion (V20). We only receive the best of the best from God. The least we can do is give Him our best.
