Actually, there is a loophole in unconditional election type theologies that poses the same two problems constantly huled at decision theology; and that is the issue of "Perseverance".
Even though on the surface it speaks of God's securing (keeping) the elect, the way is described in practice, it is the individual who himself must "persevere" in order to prove himself being "elect" after all; regardless of whether he once "professed" Christ. And it is often not so much even perseverance in faith, but rather in "holiness" (works)! (This is one reason many Calvinist groups could be just as legalistic and intolerant as any Arminian fundamentalist, and even moreso. The Arminian will condemn many things people, including Christians do, and "preach hellfire" at the unsaved, but at least they are less likely to assume a professing Christian is unsaved!). Once again, the ball is placed in the individual's corner, so after all the insistance that we cannot even choose to be saved, let alone be elected by "works" we end up earning the final realization or "proof" of salvation by works! Calvinists and Lutherans would probably deny this, but this is how their leaders have expressed it, and Calvinists here along ago said that our belief that we are elect is "fallible"— any one of us may have "believed in vain", and fall away, proving we were not elect at all. Calvin himself went on to say that God strings such people along in the belief that they are saved. Is that what you call "eternal security"? This is connected with them warning people about Hell when it is supposedly already decided, as was mentioned earlier.
Then, Luther goes into the old "intellectual suicide" copout standby of not being able to know "the
dreadful hidden will of God, Who according to His own
counsel, ordains such persons as He wills to receive and
partake of the mercy preached and offered. This will is
not to be inquired into, but to be reverently adored, as by
far the most awesome secret of the Divine Majesty", admitting that it is nit discussed in the scriptures.
First of all, he is so worried about people "burden[ing] man with a load he is totally incapable of carrying", yet agrees with Calvin that in scriptures like Deut. 30: 19 God is deliberately commanding man what He knows they cannot do, implying of course that He grants only some the abolity, withholds others, yet still "hold them responsible" as if they WERE able to do it. Isn't that a WORSE "burden" than anything choice theology places on man.
But in hypothesizing all of this, with deliberate acts of reprobation or preterition as a neccesary corrollary for God to receive all the credit of the salvation of the elect, we have already inquired into the unknowable.
(How God can be responsible for salvation when not all are saved). Why do all that, and only THEN try to plead ignorance when people question why? That is the danger of the Unconditional election theology.
