As I said, I do not have the knowledge that many here have, but it seems to me that its easy enough to read someones word, seek the Lord in prayer, read the Bible and glean from it what the Lord would have for you. Perhaps some of Finney understandings were building blocks that God gave him for others to come along after and build upon for the body as a whole. Is this not possible, that he might see and understand what the Lord had for him at that point in his walk and life. Is it not possible that God did not have for Finney to know and understand all because another member of the body was to come later and share what the Lord was doing in that persons life and have for them to share that with others?
I think the knowledge you have and share here is worth its weight in gold, Finney wrote much all belivers can draw from, so did ravenhill, luther and all the rest, all of them probably had some error somewhere, but as you say, compare it with the word of God and draw out from the main source what God has for us.
What should scare us is if what we believe today, or what we have learned the first three or four years from our conversion should be the exact same beliefs we hold when we are 50 or 60, we may have the same doctrines somewhere, but much will be shaken by the lord to show us mainly our pride, and showing us, all of us who love to study, his word, commentaries and all the rest, all those will God humble because we all have the flesh that like to feed from the tree of good and evil. so God must bring us to the place where we start seeking the tree of life, and if God is successful we will no longer box our self in in a limited understanding, we will lift our hands and fall on our face and say the closer we come to God the less i know what is right and wrong for others, but i know for me and my walk, myself was and still is a lover of theology, i love reading, i can sit with six or seven books, commentaries, interlinar bibles three or four bibles, english , swedish and my desk is packed with books, my wife says i am crasy and have never seen someone read the bible like me, but i love it.... but sadly the most i have done is gaining and eating for my mind, most of my study was wrong, no matter what i found out was right it was based upon the wrong thing, God spoke to me and said that it is not how much and how rightly i know the word, it is how transformed i become into his image that will count on that day, if i am christlike or not in all areas of my life, whether i know theology and right doctrines will not matter as much as how much i loved god and people, how i used my tongue and how pure my thought life where. And when i first was converted, i was in a pentecostal charasmatic church that preached the love of god and easy belivism as is rampant today, zealous for the new life i started reading, listening to washer, ravenhill , and found si and started reading the old classic, i read bonar, ryle, matthew henry, i read luther, i read calvin, i read mostly reformed writings, and i held to reformed theology, i did read others to, tozer etc and wesley... but i knew it all, and i was so fed up with easy belivism i went to the other side, as a reaction to the absence of hellfire preaching, repentance, decipleship etc i saw this in the old writings, in the puritans and i said to myself and all others this is the truth! and much of it was, but my heart was not right, my words maybe where, my doctrine maybe was according to some. but my heart was drawing further from the lord every day, i started slowly gleaning less and less from scripture and directly from God, and more and more from other men, from times in prayer and devotion with tears of joy and grief to a just studing what other men written, the tenderness went away from my heart slowly but surely, for a while i thought i was the only one in my surrounding that understood the scriptures, i was blessed God rooted out this pride, i still suffer from this today, but God is good, he showed me when i put away all books, all commentaries, even the bible for a short while and just gave up all i believed as doctrine and etc, after some time i took out the bible and asked i would see what God wanted me to know, not what i wanted to learn, so that i could be like Christ, so that Gods will could be worked out in my life and that i would not have a single regret in that final day. The result was every single doctrine i was super sure of, i think i could have died for my faith and doctrines rather then deny them, but in all of them, i found i had wrong understanding, maybe not the whole doctrine, but some aspect of it, one example is repentance, i was super sure what it was and how it worked out, but when coming with a fresh eye and a humbles spirit i saw new things concerning repentance, that i did not see before, and so i did with all things, predestination, election, heaven, hell but most wonderfully i saw new things of Christ....
if i had contiuned to feed from the wrong tree i would have missed these views of christ, these lovley marvelous sights of the king of glory for a doctrine, even a right doctrine, just as the pharisees did, they had all doctrines 100% right, yet missed God, this is in scripture for our learning, and i hope, in 50 years if i live and the lord tarries, that i would see much more of him, so i can be transformed into his likeness.
Also i found out that when we have the right view of Jesus, the right view on salvation, on doctrines, when we have the truth...it will set us free from sin, outward and inward, we will be more and more free, if not so, we probably do not have the true doctrine of Christ.
this must be our private litmus test, this doctrine i believe is the truth and the only gospel, is it freeing me from sin daily? is it making me more and more like Christ? more loving, more humble in my speech, more thoughtful before saying something, less self centered and more giving etc etc....
whether you or i am a calvinist or an arminian or whatever, if you find your doctrine have this effect, please continue to hold it, if not, if you find no change, no victory over sin given by God, you find unclean thoughts, evil thoughts towards others, attitudes and mood swings, lusting after money etc... you are in error somewhere most likely.
anyway, allowing God to humble us is not always a feel good thing, but it is worth it.
Lift up your heads, O you gates! And be lifted up, you everlasting doors! And the King of glory shall come in. (Psa 24:7 NKJ)
God bless you all
