I know well you do not understand the significance, that is because you have learned your doctrines of grace from theologians, they are not bad theologians but they have an assumption in their theology.
Calvinism is a sweet ointment to those who understand Predestiny and Election by it.
But there is a fly in the ointment and it giveth off an evil odour.
This is the assumption.
Calvin ASSUMED that since God predestined some to be [saved] He must have predestined all others to be damned. This is called popularly Double Predestination.
There is not a scrap of bible support for it.
It does seem logical I admit, but first of all you will see if you check out Paul's teaching on predestiny it is not unto salvation. We are predestined and chosen to be conformed to the image of God's dear Son, once again we are predestined and chosen in Him before all worlds began to be for the praise of His glorious grace.
We are the lamp lit not to be hidden under a bushel but to give light to everyone entering the house, a city set upon a hill...what a wealth of instruction is here.
Abraham was predestined and chosen to bless, all the families of the earth will bless themselves by Abraham...and this has come true.
I do not deny eternal punishment or that some are destined to it, but predestiny is something different, predestiny says that this was the way God planned it to be..a'la' B57 [darkened soul] now if we are to be light, and if we are to be a city built upon a hill it is that others may see and others may seek and find us. We are to bless not to curse which is what double predestiny does.
We must be saved in order to be conformed to the image of God's dear Son....but that does not preclude others from being saved.
Why do you throw up your hands in horror because I say God closes eyes that they see not, and stops up ears that they hear not...that is the very scripture. That FULLY explains Particular Redemption...yet you say Particular Redemption is achieved by limiting Christ's atonement...and that does not horrify you.
The bible supports what I say, for no man can come to the Father but through the Son...it says stitch about Limited Atonement.
