The people of Israel was chosen by God among all nations, but this did not make them a people without mistakes. When we read their story we realize that they have strayed from the path many times, going behind idols, and because of that is why we are going to see a constant struggle of the prophets telling them to turn to God.
Ezekiel in his book describes the people of Israel as a hard-hearted people: “I, therefore, send you to sons with a hard face and an obstinate heart, and you will say to them, ‘Thus says the Lord Yahweh.’ (Ezekiel 2: 4) This people lived falling and falling, but God always urged them to return, through the prophets and judges.
God did miracles, wonders and signs for them that only reading them makes a great impression on us, and we ask ourselves: Were they still so hard? And it does not stay there, Jesus on the other hand also performed miracles that had never been seen before and yet this people crucified Him. Do you realize how far the hard heart of the people of Israel has come?
