“For this commandment which I command you today is not too difficult for you, nor is it out of reach” (Deuteronomy 30:11).
Federal Visionists love this verse because they think that the covenant that God made with Israel was not too difficult for them, nor was it out of their reach. They argue that the covenant was to be kept by faith. Obviously, this is utterly Pelagian.
The Reformed faith has always insisted that covenants can only be based upon grace or works. A covenant based upon grace is entirely a gift, and thus, it is unbreakable. A covenant based upon works is kept by perfect obedience. These are the only two paradigms for covenants in the Bible.
Thus, the Reformed faith has always held that the Mosaic covenant was a re-publication of the Covenant of Works. As such, it required strict obedience. If Israel failed to perfectly obey, then they broke the covenant.
This is precisely what happened. As soon as the covenant was made, undoubtedly one of the Israelites sinned and broke the covenant. In fact, before Moses could finish reading the requirements of the covenant, Israel had probably already broken the covenant.
Thus, God could enjoy the farcical moment of Moses writing that the covenant was “not too difficult nor out of reach,” when in fact, the covenant was already broken. In reality, the covenant that God made with Israel was far too difficult from them. It was far, far out of their reach.
