Was Jesus' offer to Israel to be their King and Redeemer a real, valid offer?
Yes. When Christ came and presented Himself as the King of Israel, it was a valid offer. He came to His own to be their Redeemer and King, but they rejected it. That rejection fulfilled eternal purposes, bringing salvation to the whole human race by faith alone, apart from Israel, the Law, the Temple, or proselyting.
Les explains that when Christ came and presented Himself as King of Israel, it was a valid offer. He came to His own to be their Redeemer and King, but they rejected it. That rejection fulfilled the eternal purposes: salvation to the whole human race without Israel, without the Law, without the Temple, without proselyting. It was salvation by faith, and faith alone. Les also notes that Christ became the curse, hung on a stake as it were, like Deuteronomy's wayward rebel son, so that the blessing of Abraham might come on the Gentiles, not through the salvation of Israel, but through Jesus Christ. He urges balance between wild emotionalism and staid religionism, and says believers have reason to be happy and joyful, yet must do things in order.
