Covenant by Sacrifice
Ps 50:1-6(KJV): The mighty God, even the LORD, hath spoken, and called the earth from the rising of the sun unto the going down thereof. Out of Zion, the perfection of beauty, God hath shined. Our God shall come, and shall not keep silence: a fire shall devour before him, and it shall be very tempestuous round about him. He shall call to the heavens from above, and to the earth, that he may judge his people. Gather my saints together unto me; those that have made a covenant with me by sacrifice. And the heavens shall declare his righteousness: for God is judge himself. Selah.
In the scripture above the Lord speaks of saints in Zion, which is symbolic of the perfect Church, who have made a covenant with him by sacrifice.
What then is this covenant and how do we make it by sacrifice?
The covenant is having the laws of God permanently inscribed in your heart by the Holy Spirit:
Hebrews 8:10(KJV): For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people:
We make this covenant by the offering of our physical bodies as a living sacrifice by the mercies of God:
Romans 12:1(KJV): I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service.
We make a conscious and deliberate presentation of our physical bodies as a living sacrifice to God to keep our bodies pure and holy by the mercy of God, through the power of the Holy Spirit by prayer and the Word.
We renew this vow daily by daily resolving to keep ourselves in the love of God.
In doing this, as we fellowship with the Holy Spirit in watchful praying spirit and daily balanced bible reading, the laws of God are gradually permanently inscribed in our hearts by the Holy Spirit and so we make covenant with God by sacrifice.
