Written Upon Our Hearts
Jeremiah 31:33 (ESV) … “For this is the covenant that I will make with the house of Israel after those days, declares the Lord: I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people.”
Thoughts - Jeremiah 31:33 reflects the fact that the Mosaic Law and the Levitical priesthood with its Temple services had failed to produce a people of righteousness. Therefore, Jeremiah was sent to prophesy the doom of the nation of Israel, judged by God because of their disobedience and idolatry. The covenant that God made with Israel at Sinai had failed. Because the Law could not bring redemption to men, a new way was found. In His divine foreknowledge, God was preparing to make a new and better mankind covenant with men, which would be through the blood of His Son Jesus Christ. This time, the Holy Spirit would be poured out in the men’s hearts, so that the Law could be written in their hearts, transforming them from within, enabling them to stand righteous before Him in the heavenly Tabernacle.
Scripture Reference - Note the following Scripture references:
Ezekiel 36:27, “And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them.”
Joel 2:28, “And it shall come to pass afterward, that I will pour out my spirit upon all flesh; and your sons and your daughters shall prophesy, your old men shall dream dreams, your young men shall see visions:’
Application – This new covenant with God is not written in black ink on white paper, it has been written in bright red blood of Jesus upon our inward hearts. How has this new covenant transformed us? Do we live up to the privilege of what God has given us in a new righteousness?
