I absolutely agree with that one; known unto God are all His works from the beginning of creation. Yet, God glorifies Himself despite the disobedience of the vessels He chooses to use, eventually bringing them to an even better state of usefulness/spiritual fitness.
The story of the birth of the nation of Israel is a mess; Joseph was sold into slavery; David sinned with Bathsheba, etc, etc.
I believe when God gives a commandment, He provides everything needed for its carrying out, along with the commandment.
I'm reminded of Israel's rejection of Christ at this point. He came unto His Own, His Own received Him not... Yet Jesus wept over Jerusalem, and rebuked the nation for not recognizing the hour of her visitation. Any such emotions and rebukes wouldn't make sense if there was no viable offer of the Kingdom, and a real possibility of Israel's accepting the offer.
I believe this discussion comes very close to, or even becomes, a dispute on the subject of election and that is one of the most controversial topics in theology.
Blessings.
