Exodus 25: 1,2 :
Then the Lord spoke to Moses, saying: “Speak to the children of Israel, that they bring Me an offering. From everyone who gives it willingly with his heart you shall take My offering…”
This very offering went on to be used to construct the Old Testament Tabernacle, including the ‘most holy (place)’.
Romans 12: 1 :
I beseech you therefore, brethren, by the mercies of God, that you present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service.
Tell me, what can’t God do in our lives as we willingly offer them to him… becoming living sacrifices?
It’s all there… read it for yourself.
