When will Israel's covenants be fulfilled?
Israel's covenants will finally come into fruition during the tribulation, the time of God dealing with the nation of Israel. They are Jew-only covenants and have nothing to do with the Gentile or the church, so they are not fulfilled in the church age. Jeremiah 30 describes that time of trembling and fear.
Les explains that the tribulation is primarily God dealing with the nation of Israel. He says you cannot run the church into God's dealing with His covenant people because the church is not under any of these covenants. These covenants are Jew only and have nothing to do with the Gentile. They will finally come into fruition when we get over into the tribulation, the time of God dealing with the nation of Israel. He connects this to Jeremiah 30:5, which speaks of a voice of trembling and fear, not peace, and says the horrible events will be centered in the Middle East and directed primarily to the children of Israel.
For thus saith the LORD; We have heard a voice of trembling, of fear, and not of peace.
