2) the Person of the indwelling Holy Spirit (yielding to His leading,)
3) the Scriptures and
4) the Creation (both spiritual and physical.)
That is Truth for me and everything else is a distant second, third, etc. - including sensory perception, reasoning, counsel of mentors, etc.
IMHO, everyone has a starting position whether he realizes it or not. Surely it would help all of us to be aware of our presuppositions.
For instance, some around here seem to elevate Aristotlean logic above revelations of God in certainty and therefore demand that God must be "logical" in their own eyes.
Others seem to put sensory perception first, like doubting Thomas - they are only certain of what they can see, hear, touch, etc.
Still others seem to be more certain of the counsel of their trusted religious leaders.
Perhaps that should be a topic for a Religion Forum research project? Where are you "coming from?" LOLOL!
Gotta coin? I think a lot of decisions are made that way as there is a lot of inconsistent thinking as well.
