Jeremiah 31:33-34
"But this is the covenant I will make with the house of Israel after those days," declares the Lord, "I will put My law within them, and on their heart I will write it; and I will be their God, and they shall be My people. And they shall not teach again, each man his neighbor and each man his brother, saying 'Know the Lord,' for they shall all know Me from the least of them to the greatest of them," declares the Lord, "for I will forgive their iniquity, and their sin I will remember no more."
The writer of the Epistle to the Hebrews quoted this extended passage, so I think God wants us to know this. God will never abandon the Nation Israel. God made them promises that will not be transferred to any other people.
This passage tells us about a future time when Jesus has assumed the Throne of David and will reign as King over the whole Earth. He will not just give them His laws, as He did at Mount Sinai, but will change their hearts by the New Birth, and no one will need to tell anyone else who Jesus is, everyone will already know Him, not just know of Him.
They will all know in their hearts the right way to live their lives, and how to build healthy relationships with one another; they will all know God's love for them, and will love and worship Him and love one another with His love; and they will all know God's forgiveness, and be able to grant that forgiveness to themselves and to one another. It will be Earth's Golden Age.
Today let us live our lives knowing Him, loving Him, and extending His love and forgiveness to one another, in the power of His Holy Spirit that lives in us. That's what Jesus meant when He talked about the Kingdom of God being within us. He is our King and we obey Him as His subjects today, being in the world but not of it. And eagerly waiting for His Glorious Appearing.
Even so, come, Lord Jesus!
