“Behold, days are coming,” declares the LORD, “when I will make a new covenant with the house of Israel and with the house of Judah, Jeremiah 31:31
God has continually promised that a “New Covenant” would be established. So why did we need a New Covenant? Originally God made the first Covenant with the nation of Israel, through Abraham he would bless them and multiple them as many as the stars. However Israel continually cheated on God with many other gods. They were also non repentive of all there sins.
God gave the Jewish people The Law as a compass to live righteous and holy lives. However because of our sinful nature, they were unable to keep The Law. Therefore God gave us a redemption plan for not only the Jews, but all of humanity. That redemption plan is Jesus Christ
And in the same way He took the cup after they had eaten, saying, “This cup which is poured out for you is the new covenant in My blood. Luke 22:20
The New Covenant was established by the shedding of blood by Jesus Christ, who became the ransom for our sins. Even though we were still sinners Christ died for us. This New Covenant opened the door for anyone, not just Jews, to become Children of God.
But we can only be saved by the Grace of God through Jesus Christ. Repent on your sins, confess Jesus Christ is your Lord and Savior, enter into the New Covenant Amen!
