I believe that the Scriptures are a FORM of the word of God . . . and I believe that they are the most trustworthy form.
I also believe that a prophetic announcement is a word from God . . . although not to the same standard (I can explain if you so desire).
But this still doesn't change the facts about the Greek . . . true that the Spirit who penned the words is indespensible in the process of faith and understanding the Scriptures . . . but the way that He moves in enlightenment is varied. For one, a simple perusal of the text is all that one needs and the Spirit has accomplished His will . . . but for another the will of the Spirit drives him/her deeper into the text and as close to the original conveyance as possible (like me) due to the standard that God has called one to.
The written scripture is certainly a guide and very 'trustworthy', and perhaps also as you say a 'form of the Word of God' but with the scriptures and man's apparently flawed discernments we have today literally thousands of 'Christian' churches, assemblies, groups, etc. Is it the 'most trustworthy form'? If that is the case then what did sincere believers do after John Beloved was gone but before the New Testament was written and distributed?
I have idea of what you mean, but would appreciate your explanation of your declaration: 'I also believe that a prophetic announcement is a word from God'.
Many of the initiating leaders of many existing Christian denominations today probably started as Martin Luther did, not wanting to start a new church, but rather to bring the current one closer to God. Unfortunately, not all of Luther's followers and not all of the followers of other sincere leaders of church groups had the same purpose as the leaders themselves. The difficulty with even a group established on a correct premise is that people like to find a nice comfortable place to sit with all of the answers already in place and carefully organized so they have immediate access.
This type of careful organization may work well for most business groups, but not with God's people. We can never sit comfortably back with a box of index cards with all of the answers or even a computer file with all of the answers. All of the answers are in His Word, Yes even in His written Word for us. But..there is not index that has all of the answers we will ever need. The search MUST continue until...until we have reached the end of our course. No vacations and no retirement from God.
For you the answer, or at least an answer, to finding the most Truth from the Bible is in understanding the original Greek. I won't disagree that this could be helpful and for you may be the best and even the necessary way. This is, however, not within the means or ability of every person seeking God. The Truth is not limited only to those persons with means to get into the Greek texts. It is rather to 'whosoever will'.
As to always getting something from the perusal of the written scripture, I would not be so definite even about that.
Yes, I agree that reading and studying the written Bible is very important and I strive to do just that every day. Yet, I have known at least one self-proclaimed atheist who knew more scripture than many self-proclaimed Christians and was able to support his position very logically using the Bible. A person can use the scripture to proof almost anything that he chooses, even that God does not exist.
[Of course, a servant of God who is seeking the Truth continually will have no trouble from such an educated atheist, but how diligent are many Christians in their pursuit of Truth?]
The key for me is in the need to bring the Bible to Life with God's help. You have apparently found a way to do that through your study of Greek, and that is fine for you. I would never presume to say that God would not use that. But neither would I presume to say that without Greek a person is limited.
The most important thing I see is to start at the bottom every time I start to talk to God or to study His Word or to do anything with regard to God. If I head for the pulpit instead of the altar at each approach to Him, I will probably get into more trouble than I am able to handle.
"When thou art bidden of any man to a wedding, sit not down in the highest room; lest a more honourable man than thou be bidden of him;And he that bade thee and him come and say to thee, Give this man place; and thou begin with shame to take the lowest room.But when thou art bidden, go and sit down in the lowest room; that when he that bade thee cometh, he may say unto thee, Friend, go up higher: then shalt thou have worship in the presence of them that sit at meat with thee.For whosoever exalteth himself shall be abased; and he that humbleth himself shall be exalted." Luke 14:8-11
Actually, I find very little on which we really disagree.
Give God all of the glory always!
