I strongly disagree with the idea that this text does not teach God actively reprobates the nonelect. Christ also speaks of this in the New Testament. He had to deal with blinded eyes, and stopped up ears. His minstry was to be rejected by the House of Israel that he came to save. Christ and John the Baptist acted as Covenant Lawyers (to borrow M. Kline's term) and condemned the unfaithful servants of Israel. What little had been given to the unfaithful servants was given to the faithful with more blessings added upon it. Israel was divorced eventually, cut off from the Olive tree. This should sober us as Paul teaches in Rom 11 we ought to be afraid less God cuts us off from the covenant head, Yeshua.
