In the Old Testament God chose someone and appointed him to serve under his authority the remainder of his lifetime. After God selected this person, God sent a prophet that poured a generous amount of anointing oil on the person head. This anointing meant that God had ordained them and had given them power and authority to do something specific.
Now if you obey me fully and keep my covenant, then out of all nations you will be my treasured possession. Although the whole earth is mine, you will be for me a kingdom of priests and a holy nation.' These are the words you are to speak to the Israelites." Exodus 19:5-6
People were not the only things anointed. The tabernacle equipment were anointed and set-aside for sacred specifically used for worship of God. The plates, tables, lamps, forks, spoons, in fact everything including the structure of the tabernacle that was used for the worship of God was anointed with oil.
Aaron's sacred garments will belong to his descendants so that they can be anointed and ordained in them. Exodus 29:29
Make these into a sacred anointing oil, a fragrant blend, and the work of a perfumer. It will be the sacred anointing oil. Then use it to anoint the Tent of Meeting, the ark of the Testimony, the table and all its articles, the lampstand and its accessories, the altar of incense, the altar of burnt offering and all its utensils, and the basin with its stand. You shall consecrate them so they will be most holy, and whatever touches them will be holy. Exodus 30:25-29
In addition, both High Priest and Israelís King were anointed and ordained with this sacred oil. Many times God sent a prophet with a flask of oil to pour over the personís head ordaining him to do something special. Anointing was the initial act that ordained Godís chosen man for the rest of his life. Whether it was of priest or kings those anointed received a commission that was passed down to their descendants as an inheritance.
Those anointed and chosen by God were set apart and had Godís authority to affect the lives of men. God demanded that these men live holy lives keeping the word of God close to their hearts. Those who chose not to live by the moral standards of God were stripped of their positions.
Aaron and his four sons Nadab, Abihu, Eleazar, and Ithamar were the first priests to be anointed. They were first washed, given clean clothes to wear and then anointed. When Nadab and Abihu failed to honor God by offering improper incense, God struck them down and they were permanently removed from service in the tabernacle.
Elisha wanted a double portion of Elijah anointing so, God honored Elishaís choice to succeed Elijah by anointing him as prophet. Long after he died two dead men were thrown into his grave and they came back to life.
The majority of men anointed as King of Israel were not above reproach but were taken in the condition they were found. Saul was sleeping in the traveling supplies, David was shepherding his fathers sheep and called in from the field, Solomon was anointed while his brother was claiming to be king, And Jehu was drinking while taking a break with his comrades when Godís prophet anointed him king.
The LORD has sworn and will not change his mind: "You are a priest forever, in the order of Melchizedek." Psalms 110:4 Hebrews 5:6
Under the new covenant some things remained the same, yet God is still building a Kingdom of priests that Peter calls a royal priesthood. In this covenant, Christ has become the High Priest in the order of Melchizedek. In this role Jesus Christ like Melchizedek became the person chosen to anoint those God has called into his service. In Christís case, his appointment was not based the law or his ancestry, but on an indestructible life. Because of his indestructible life he can serve God and mankind for an eternity.
God anointed Jesus of Nazareth with the Holy Spirit and power, and how he went around doing good and healing all who were under the power of the devil, because God was with him. Acts 10:38
John spoke of another anointing specifically with you in mind.
But you have an anointing from the Holy One, and all of you know the truth. 1 John 2:20
Paul explains it this way.
Now it is God who makes both us and you stand firm in Christ. He anointed us, set his seal of ownership on us, and put his Spirit in our hearts as a deposit, guaranteeing what is to come. 2 Corinthians 1:21-22
You are the holy one God has chosen and appointed to a lifetime of service under his authorit. This anointing that sets you apart for Godís service is called sanctification. By anointing you, you have been given the authority and have been empowered make disciples by taking the gospel message wherever you go. This also gives you the assurance that God will protect you while you are doing his work. Take this word to heart.
But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth." Acts 1:8
God anointed Jesus of Nazareth with the Holy Spirit and power. In the same respect Jesus Christ baptizes you with the Holy Spirit and with power. With this honor, God has placed you into his kingdom as a priest forever. Let us remember that God's gifts and his call are irrevocable. Romans 11:29
Letís remember that Jesus Christ has also ordained you as a king to rule under the leadership of God. Like Elisha, this is a role that you choose to accept and one that you find to be an outstanding way to live.
