Is God's Master Plan for Salvation, Amen?

Calvinists believe that god is a preordained, predetermined who will and won't be on the team in the church. This passage can also be divided into three sections, each of which focuses on a different person of the trinity. It's like he's saying a bunch of really good things that i would say, ye, that sounds about right. And then al of a sudden he just jumps in there and goes, god has already pre planned and pre written in eternity. Where does it say that here? That's what i've just got to ask yonotice, that's john mc arther, not bible.
