Let us dive into the meaning of consecration. Consecration simply means to be set apart.
When we read the book of Genesis, we are introduced to two individuals, Adam and Eve. Adam and Eve lived in the garden of Eden where the Lord had provided for them everything they needed in the garden and He would fellowship with them in the garden (Genesis 1:8). This is the first instance where we see God setting apart human beings to have a relationship with Him through fellowship. And this culminates concentration for they were given a rule by God. In order for this consecration to remain, they were not to partake of the forbidden fruit for this in turn would lead to their death (Genesis 2:17) and we all know what happened after, they ate of the forbidden fruit and this in turn led to their separation from the place of consecration with God and they had to live a different life from the life they were set apart of by God. They no longer had a physical relationship with God, where God would physically visit them (Genesis 1:8)
Yet God still desired to communion with men for we see that even though they were removed from the garden of Eden, God would still talk with them (Genesis 4) and an element of sacrifice is introduced to them as a form of fellowship with God.
And as we continue to read the book of Genesis, we see the calling of Abraham, where he was set apart from his people and taken into a different land that God showed him where he would birth a nation consecrated (set apart) for God. And this nation was none other than Israel.
Throughout scripture we see how God was with the people of Israel and how the Israelites were very different from the rest of the nations, who were called gentiles. The Israelites performed different rituals, had festivals, offered sacrifices and believed in only one God and we see that God was with them throughout their journey. The Israelites lived a consecrated life for they were a group chosen by God to show His greatness and reveal His nature to men.
It was in these people who God had consecrated for himself that our Lord and Saviour Jesus Christ was birthed into. For God had chosen and consecrated them to Himself and that is why we have up to date the people of Israel and not the people of Moab, Philistia or Canaanites.
And it is through our Lord and Saviour Jesus Christ, that we now too who were considered not His people have now become His people (Romans 9:25). We get to enjoy the privilege of becoming God's chosen people, His children, a people set apart/consecrated to and by Him.
Oh what a joy it is to be counted as one who serves the Lord
Oh what a privilege it is to be counted among the righteous
To be deemed a people consecrated before the Lord.
Rejoice you sons and daughters
Oh rejoice before our King
For He is good, great and mighty to be praised.
