I get that part of your belief, but I am looking for the "ordained" explanation, or am I just not understanding you?
The Greek term "horizo" means to mark out the boudary lines. It is where we get our English term "horizon." The horizon encompasses all that one can see. No one can see beyond the "horizon."
When this term is contextually linked with God and His purpose it refers to all that God has determined and is committed to "working all things together" with a certain determnation in view - "according to His Purpose." (Rom. 8:28-29).
Romans 8:28-30 is often misintepreted because of failure to note the beginning verse (v. 28) and the final verse (v. 31) which deny that mere prescience or knowledge of future events are the "horizon" in view.
Verse 28 clearly and explicitly states there is a DETERMINATION in view where God is actively "working all things for our good" while verse 31 explicitly states this determination in the words "If God be FOR US who can be against us."
In addition ALL whom God is working for good are ALL whom He has foreknown according to that determinate purpose and all whom he has foreknown are predestinated to be conformed to the image of His son. Hence, not one foreknown is predestinated to that "horizon" or end! That means ALL who are called are ALL justified and are ALL glorified and this is what constitutes the basis of the question "if God be FOR US who can be against us?" The necessary inference is that N

NE can be against us if God has DETERMINED to be for us because He is determinately working all things for us "ACCORDING TO HIS PURPOSE" and as Isaiah says, "What I have purposed, I WILL DO it."
