In Revelation 1:5b-6 it says 'To Him (Jesus) who loves us and has freed us from our sins by his blood, 6 and has made us to be a kingdom and priests to serve his God and Father--to him be glory and power for ever and ever! Amen.' According to this verse whoever has trusted in Christ for salvation is now a priest. In the Old Testament, the priests were from the tribe of Levi, and their whole existence and inheritance was wrapped up in serving God.
I was studying recently about the different types of offerings that the priests helped with at the tabernacle. There was the burnt offering where the whole animal was burned and it signified dedicating your life to God. There was the grain offering where you offered the first fruits of your harvest to God out of gratitude. There was the peace offering where you sacrificed an animal and part of it was shared as food for the priests and it symbolized fellowship and peace among you and others. Lastly there was the sin offering and the guilt offering that were animal sacrifices where the shed blood of the animal paid for a sin (unintentional and intentional) that you committed.
In these offerings I saw some different pictures of worship. Just like the burnt offering, worship is about dedicating your whole life to God or offering yourself as a 'living sacrifice' as it says in Romans 12. Just like the grain offering, we worship God by giving back to Him for He is the One who has given us the talents, abilities and energy to work and make money.
Just like the peace offering, we worship God by being at peace with one another and loving the people God has placed in our path and life. Just like the sin and guilt offering, we worship God in honesty, confession and repentance and realize that sin not only affects others but it first and foremost is against God Himself.
So, in what ways do you need to worship God today? May your worship be full and meaningful and life-changing.
