Well, this is the dilemma facing Church. Every denomination seems to have it's own peculiar interpretation of this Bible doctrine. The interpretations, views and narratives are radically different. There's a smorgasbord of interpretations and everyone chooses the one which appeals most to their views.
I'd rather not get into a long and drawn-out debate abut which interpretation is the Biblically correct one. Because highly educated theologians have been debating this topic for around 500 years and they are no closer to finding any common ground today as they were when they started.
I don't think anyone can convince someone else to agree with their private interpretation of those texts. Thankfully the Church doesn't persecute people for having a different view today as it did in times past. Today we can choose a local Church, where we agree with the view of the Minister.
I did a lot of shopping around and found a Church where the preaching lines up with my understanding of the Bible. I guess everyone does the same, so we end up with countless denominations and opposing views and everyone thinks theirs is the only true one and all the others have errors in their interpretation.
After shopping around for a couple of years, I settled into an independent non denominational Reformed Baptist Church. So to answer your question regarding context, I would refer you to the 1689 Reformed Confession Of Faith

The confession outlines the reasons we believe in Gods sovereignty in election and predestination.
