jari, I am replying to your post #75.
I don't know of a single Bible example of a false concept of God perpetuated by the Holy Spirit. He can't possibly have more than one influence doctrinally while remaining One with God. If a man stands by the Spirit, we know by the Word of God what to expect. Holy men of old experienced the Holy Spirit, all to the same expected results. Even Judas Iscariot experienced Him, taking part in the fulness of the ministry of Christ. Under His influence the expectation is the same. How a man ends up is another thing.
By "mature" Christian I point to the Greek pater for father as used by John in 1 Jn 2. It is obvious John was addressing various levels of spiritual maturity. Each level is expected to experience some degree of "enlightenment" from God. The Greek for "tasted" is geuomai, to experience good or bad, to know the nature/character of something. I watched a cooking class on FoodNetwork and heard the chef ask the audience "Have you tasted the possibilities of saffron?" Well, I had not heard of that spice, so no, had not experienced it. After learning about it I bought some and we are enjoying it here and there. It's delicate, nice, very expensive and hard to find, and hard to notice rightly. In the same way Jesus demanded in John 6:53 Then Jesus said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you.
There is a "tasting" of many things concerning human existence, as well as life in Christ. Probably most of us miss most tastings, but hopefully not tasting of the word of God.
On to your next point. I worked alongside a brilliant geophysicist concerning a wetland area that was drying up. Along came another expert that cautioned me the fellow was but a second year grad student (but had studied at least ten years and had worked for Shell Oil all along), himself having achieved a PHD in that field 20 years earlier. It was apparent he was not keeping up with technology, but we respected him anyway. The young man keeping up was a fresh breeze of inspiration, but didn't have the gravitas of the older geologist. I took the younger's advice mostly. In the same way a person who is freshly connected to the Holy Spirit ought to be at least as inspiring to us and a sage of the faith, both being led of the same Spirit. But sometimes a sage might have become a bit deaf to the voice calling to him many years. Anyway, the qualifications of Hebrews 6 fit a sage of the faith, one who has experienced the fulness a human could expect to know in this life. A newly converted believer hears the same voice, but might require many years of experience and study to taste what the mature Christian has tasted of.
As for "reading" a scripture depending on how one believes a related doctrine, I avoid doing that. I look at all the context, not just the individual words and their original meanings, but the culture, politics, and other aspects of the days in which those scriptures were given. People around the world remain mystified over the meanings of the Bill of Rights, the Declaration of Independence, the American Revolution, the "War" between the States (Civil War), and other beginnings of American society because they lack the historical/cultural basis around each event. Well, unfortunately today many Americans lack that background knowledge, so can't appreciate those events.
I caution against "reading" any portion of scripture in light of some denominational dogma or personal belief that hasn'tr been tried by the fire of the Word of God as a whole. If a doctrine/dogma is proper, it won't be contradicted by other scriptures in context.
Your fourth point really has to do with the efficacy of the blood of Jesus. It is equally powerful to wash past sins, but also ready to deal with a person who hasn't even been born again. The blood will wash him too if he meets the conditions of salvation. There are conditions involved, including belief of the gospel, repentance, obedience. The toughest part to comprehend is the repenting. Going back into a sin that one repented of presents some serious theological problems. It's one thing for a cleaned up believer to fall into occasional sin, then repent, forsaking that. It's quite another for that believer to keep falling into a sin washed by the blood. Taking that up a notch is that believer coming to a point of denying Jesus. Jesus said if we do that He will deny us before the Father. The more we know and have experienced, the more dangerous that becomes.
On that last point, Paul focused on those betrayers as having overturned the faith of folks by saying the resurrection had come and gone. That stripped them of their hope. Pretty serious to lead people astray like that.
