Thank you all who have answered so far.
One of the ways I would distinguish between Jacob and Israel, would be to separate them into the man of flesh and the man of faith. (I think I have more to say about Jacob than Israel, in this post.)
Just as I was coming to write, having read all the responses one after another, I also realised that Jacob was separated from his parents, brother and home, by sins; but by the time he sets off to return, it is for reconciliation.
But, not only he has changed and been changed, [i]so has his brother[/i]... 8-)
The other thing I'd say about Jacob, is he did have some [u]good[/u] points. Although his uncle cheated him by changing his wages without discussion, Jacob had done the work. He had kept his side of the deal, and he had a right to expect to be paid properly for his service.
He had understood something about the importance of keeping his word, perhaps because he had an eye on God holding him to the promise he had made Him at Bethel.
Perhaps also, this was a direct result of his merciless bargaining with Esau over the birthright. We know he was frightened enough to have run away, but did he feel guilty? I'm not sure, although he knew Esau had good reason to be [i]very[/i] angry.
However, he must have been comforted by the vision / dream he had on the night he ran away. Surely this was something special from God to him. The fact is, he had [i]got[/i] the blessings he [u]wanted[/u]. He had been jealous to be in that special relationship with God. Perhaps God [i]liked[/i] him, for this.
Perhaps God likes [i]us[/i] more than we realise...?
Then, Jacob [i]loved[/i] Rachel. Despite the fact Rachel was an unbelieving idolatress, (a statement about her heart), she was beautiful.
However, the word says of Leah that she had 'soft eyes' - which may be a commentary on [i]her[/i] heart - even if she didn't have her sister's looks.
Or perhaps, beauty is in the eye of the beholder.
But it was not until Rachel associated her barrenness with her unbelief, that she cried out [i]to God[/i] for 'children'. Yet, even after she had borne Joseph, and was on her way to meet Jacob's family, she was still an idolatress and a liar.
I think it is interesting how God honoured Jacob's love for Rachel, by making her sons eminent in the rest of Israel's story. In this, He makes a strong case for the love which [i]may[/i] hold a marriage together, despite philosophical differences. This certainly applies to ordinary marriage outside of the Church. (I'm not [i]for[/i] believers [i]setting out[/i] to marry unbelievers.)
I see this as a reference to the love of Christ for [i]all[/i] those for whom He died - not only those who have believed to date - in that we also are an idolatrous people who don't turn to God until we are desperate for something only He can give us.
In our case, it is a good thing that God thinks we're beautiful, [i]despite our hearts[/i]. I mean, when He loved us enough to die for us.
