Observation: Aaron and his sons are completing their week of purification to become the priests within the sanctuary, and it ends with a series of sacrifices. Some they present for their own absolution, and then some are presented on behalf of all Israel as part of the daily need to absolve them. In this matter, and ignoring all the 'methods and procedures' of the sacrifices - like which animals are used, what parts are waved, what parts are washed, when and where is blood spread, etc. - there are three kinds of offerings given, and these are consistently the three most common sacrifices performed.
-- Sin offering - Done to confess wrongdoing and seek forgiveness
-- Burnt offering - Fully burned up, it signifies total devotion to Yahweh
-- Fellowship offering - A means to declare relationship with the Lord
There are other types of offerings required to purify oneself after an event, or to declare a special decision in life, but these are the key ones everyone is to do regularly, if not daily. They effectively represent the daily relationship everyone is to have with the Lord. We are to seek forgiveness for our sins, declare our faith and devotion and trust in the Lord, and then joyfully make him part of our walk as our father in heaven.
Application: This model remains true today. It applies to Christians as well as Jews, and while it may not involve butchering and burning goats/cows/sheep anymore, it is a reminder of how we should all move into the presence of the Lord every morning.
I am to admit my sins and seek forgiveness, leaning into the salvation found through faith in Jesus as my comfort, knowing I am saved not by deeds but by faith.
I am to declare my full faith and devotion to the Lord, placing my burdens and hardship and resources and time and energy and thoughts before him, to be used however he would deem appropriate.
I am to embrace the fact that the Lord knows me, blesses me, holds me, and leads me, because he is my father - my abba - who loves me, and I love him and want to be in his presence every moment.
And in all this ... I am to pray, mixing my prayers into the pillar of smoke that arises in the throne room of heaven, a pleasing aroma before the Lord.
Prayer: Lord, I do seek your forgiveness for my sins, and continue to ask you for your wisdom and guidance in matters of my daily activities and thoughts. You are my Lord and my God, the only part of my life with true value, and I desire only to worship and honor you with my entire life. Please be with me this day, holding me in your hands, and showing me your perfect will. I thank you for your love, your mercy, and your blessings. May I return joy and honor and praise to you this day. Amen.
