When people leave it to what they
think the Spirit is guiding them, then they just potentially add to the thousands of various interpretations. Again,
see here.
So all answers are found in the Bible? Please show us where the Bible says that "all answers are in the Bible". It is, in fact, an impossibility since "the Bible" was did not even exist when the writers of what we call The New Testament were writing.
The Bible, in fact, teaches otherwise:
See here. That is a fact that anyone can read for himself
in the Bible.
I both agree and disagre on your last statement. Yes, we agree that the fullness of God's special revelation to mankind is in Christ, but anyone who reads the Bible cover to cover must also agree: The Bible is not (and cannot be because even it says so) the sole rule of faith for a follower of Christ.

In case you have not or will not read the "see here" links, let me clarify from "your" Bible:
2 Thessalonians 2:15
" So then, brothers, stand firm and hold to the teachings we passed on to you, whether by word of mouth or by letter."
1 Corinthians 11:2
"I praise you for remembering me in everything and for holding to the teachings, just as I passed them on to you."
2 Timothy 1:13-14
"What you heard from me, keep as the pattern of sound teaching, with faith and love in Christ Jesus.Guard the good deposit that was entrusted to you—guard it with the help of the Holy Spirit who lives in us."
2 Timothy 2:1-2
"You then, my son, be strong in the grace that is in Christ Jesus. And the things you have heard me say in the presence of many witnesses entrust to reliable men who will also be qualified to teach others."
The Bible is indeed the Word of God and without error, but neither Christ nor the Bible teach such an idea as "the Bible alone".
