Your order is wrong. Doctrine is of top importance to the apostles:
John: "If anyone goes beyond, and does not adhere to our teaching, do not let him into your house."
"He who is from God listens to us."
James: "Let not many of you be teachers, since teachers will be judged more harshly."
Jude: "Contend earnestly for the faith which has been delivered to the saints."
Peter: "Scripture did not come by men's private interpretation, but the prophets were carried along by the Holy Spirit."
Paul: "All scripture is by inspiration of God, and is profitable for doctrine, for reproof, for correction, and for instruction in righteousness."
"from infancy you have known the Holy Scriptures, which are able to make you wise for salvation through faith in Christ Jesus."
We don't even get started down the right path until we have heard the truth from the Bible, as it is the foundation of all that true Christians believe and trust in. Only the apostle Paul could boast that he received his teaching as a direct revelation from Christ, and when he compared what he learned to what the other apostles believed and taught, there was no conflict.
So if you interpret scripture based on your subjective experience, you will be deceived. Such is the mode of interpretation of all the cults. And to answer your question how am I so sure I got it right now? Because (by the grace of God) I got curious about what the Bible actually teaches, and took the time to examine it carefully, along with my familiarity of what scripture actually says, not only in the immediate context of passages, but also in the wider context of all scripture.
If you believe something you were told, because your experience
seems to concur, that conflicts with what the Bible actually describes, then your experience is wrong, or your interpretation of your experience is wrong. Scripture is not wrong, but your interpretation of it certainly could be, even if you are a true believer and received the Holy Spirit. This is absolutely proven by the fact that there are many varieties of interpretation of scripture by Christians all over the world. And when one interpretation contradicts another, then one or the other, or both, must be wrong, because scripture is in harmony with itself and obeys the law of non-contradiction.
This is why I admit that I got it wrong for 25 years, but have it right now, because I am relying on what scripture actually says, and my personal subjective experience is subject to scripture. This is why I can confidently say that I believe what scripture says, not what you say, and not what the modern Pentecostal/Charismatic movement says about the gifts of the Spirit, or what that movement says specifically about tongues.
Therefore, since Paul writes that first comes the fleshly, then the spiritual, the correct order of application of the Christian life in those 3 areas is:
1. Doctrine
2. Fellowship
3. Experience
We first must have the doctrine to correct the fleshly ideas we live by. If you don't have correct doctrine, you won't have correct experience. You cannot correctly apply the scripture to your life until you correctly interpret the teaching. This is why we cannot just use tradition, experience, and reason to interpret the scripture. Such things may be helpful, but they are fallible. We also need other elements to interpret the scripture, such as: the "historical grammatical method," familiarity with the whole Bible, memorization, among the usage of other rules of interpretation such as the law of non-contradiction, usage of words, continuity of context, scripture interprets scripture, and other such rules of interpretation that get to the original and correct meaning of the text.
One rule I have which is a very basic one, is if someone quotes a verse of scripture as a proof text to support an idea, I always examine the context of that verse to see if the idea fits well in the context, as well as fitting well within the whole of scripture. In addition to "fitting well" in the context, I use all the rules of interpretation I've learned. If the idea does not fit well, then the idea is false, since the verse quoted was taken out of its context, or another way to see it is that an idea has been imposed on the scripture. A typical mode of interpretation by the P/C (modern Pentecostal/Charismatic) movement is the imposition of ideas on the scripture. In fact, every major movement and denomination has done it, and still do it, and this is why there is little agreement on the secondary issues.
So then your religious jargon "
the baptism in the Holy Ghost according to scripture with accompanying gifts" doesn't sway me in the least, because I know by what scripture says (first), and also my personal experience with the wider context of Christianity, that such jargon is not based on Biblical teaching, but on ideas that are imposed on the scripture. In order to more fully live in the truth of God, we must be willing to "crucify" our inadequate interpretation of our experiences, the Bible, and everything else we hear and read, and "take up the cross" of learning how to correctly interpret scripture and the Christian walk by means of the disciplines of correct interpretation. Our understanding of God and of our salvation depends on it.
