Here are a few brief perspectives from outside Lutheranism addressing the subject; perhaps they can give you a direction for research. Both were produced as a response to Calvinists.
The Dutch Remonstrants:
That God, by an eternal and unchangeable purpose in Jesus Christ his Son before the foundation of the world, has determined that out of the fallen, sinful race of men, to save in Christ, for Christ’s sake, and through Christ, those who through the grace of the Holy Spirit shall believe on this his son Jesus, and shall persevere in this faith and obedience of faith, through this grace, even to the end; and, on the other hand, to leave the incorrigible and unbelieving in sin and under wrath and to condemn them as alienated from Christ, according to the word of the Gospel in John 3:36: “He that believes on the Son has everlasting life: and he that does not believe the Son shall not see life; but the wrath of God abides on him,” and according to other passages of Scripture also.
That, accordingly, Jesus Christ the Savior of the world, died for all men and for every man, so that he has obtained for them all, by his death on the cross, redemption and the forgiveness of sins; yet that no one actually enjoys this forgiveness of sins except the believer, according to the word of the Gospel of John 3:16, “For God so loved the world, that he gave his only begotten Son, that whosoever believes in him should not perish, but have everlasting life.” And in the First Epistle of John 2:2: “And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.”
Dositheus of Jerusalem:
We believe the most good God to have from eternity predestinated unto glory those whom He has chosen, and to have consigned unto condemnation those whom He has rejected; but not so that He would justify the one, and consign and condemn the other without cause. For that would be contrary to the nature of God, who is the common Father of all, and no respecter of persons, and would have all men to be saved, and to come to the knowledge of the truth {1 Timothy 2:4}. But since He foreknew the one would make a right use of their free-will, and the other a wrong, He predestinated the one, or condemned the other. And we understand the use of free-will thus, that the Divine and illuminating grace, and which we call preventing [or, prevenient] grace, being, as a light to those in darkness, by the Divine goodness imparted to all, to those that are willing to obey this — for it is of use only to the willing, not to the unwilling — and co-operate with it, in what it requires as necessary to salvation, there is consequently granted particular grace. This grace co-operates with us, and enables us, and makes us to persevere in the love of God, that is to say, in performing those good things that God would have us to do, and which His preventing grace admonishes us that we should do, justifies us, and makes us predestinated. But those who will not obey, and co-operate with grace; and, therefore, will not observe those things that God would have us perform, and that abuse in the service of Satan the free-will, which they have received of God to perform voluntarily what is good, are consigned to eternal condemnation.
But to say, as the most wicked heretics do and as is contained in the Chapter to which this answers — that God, in predestinating, or condemning, did not consider in any way the works of those predestinated, or condemned, we know to be profane and impious. For thus Scripture would be opposed to itself, since it promises the believer salvation through works, yet supposes God to be its sole author, by His sole illuminating grace, which He bestows without preceding works, to show to man the truth of divine things, and to teach him how he may co-operate with it, if he will, and do what is good and acceptable, and so obtain salvation. He takes not away the power to will — to will to obey, or not obey him.
But than to affirm that the Divine Will is thus solely and without cause the author of their condemnation, what greater defamation can be fixed upon God? and what greater injury and blasphemy can be offered to the Most High? We do know that the Deity is not tempted with evils, {cf. James 1:13} and that He equally wills the salvation of all, since there is no respect of persons with Him. we do confess that for those who through their own wicked choice, and their impenitent heart, have become vessels of dishonor, there is justly decreed condemnation. But of eternal punishment, of cruelty, of pitilessness, and of inhumanity, we never, never say God is the author, who tells us that there is joy in heaven over one sinner that repents. {Luke 15:7} Far be it from us, while we have our senses, to believe or to think this; and we do subject to an eternal anathema those who say and think such things, and esteem them to be worse than any infidels.
