They must be holy to their God and must not profane the name of their God. Because they present the food offerings to the Lord, the food of their God, they are to be holy. Leviticus 21:6
People who work in a restaurant or any other place dealing with serving food must keep themselves clean of any dirt. They are required to wash their hands on a regular basis. Many times they are required to wear gloves and a face covering.
All these regulations are to protect the food from contamination which, in turn, protects others.
The priests were told to be holy and not profane the name of God and that because they present the food offerings to God, they must be holy.
Believers are no longer required by God to offer food offerings to God as sacrifices. Food offerings were done away with when Jesus offered Himself as a sacrifice for all.
Even though a believer does not need to offer a physical food offering, there are many other offerings he may give. There are offerings of praise and worship, thanks, time, abilities, prayer and ministry that can be offered as a sacrifice unto God.
Regardless of which offering a believer is offering up to God, he must not profane the name of God. In other words, he must be holy as God is holy and not be defiled with sin in his life. This can be done by repentance and trust in the cleansing of sin by Jesus.
The call to be holy is not just in the Old Testament, nor just for priests of the Levitical priesthood, but for every believer in Jesus. Every believer is now the temple of God, which must be holy and pure for God to dwell in.
As a believer, you are expected by God to offer up sacrifices of praise, prayer and more to Him. You are now a priest before God, regardless of your position in this world.
Do not allow yourself to be defiled and contaminated with the sin of this world. Stive to be holy as God is holy out of love for God for what He did for you in the death and resurrection of Jesus. If and when you do sin, repent of those sins and fleeing all sin and be holy.
God has opened the door for you to present offerings to Him, do not profane His name in the process, but be holy.
Today I pray that you will know Jesus as your Lord and Savior; that you will repent of any sins against God; that you will be holy as God is holy; that you will present offerings to God on a regular basis; and that you will allow Jesus to keep you holy.
