2 Tim 2:14-15
14Of these things put them in remembrance, charging them before the Lord that they strive not about words to no profit, but to the subverting of the hearers.
15
Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.
1 Tim 5:20-21
20
Them that sin rebuke before all, that others also may fear.
21I charge thee before God, and the Lord Jesus Christ, and the elect angels, that thou observe these things without preferring one before another, doing nothing by partiality.
2 Tim 4:1-3
1
I charge thee therefore before God, and the Lord Jesus Christ, who shall judge the quick and the dead at his appearing and his kingdom;
2Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all long suffering and doctrine.
3For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears;
We are told to study the Word, so we can rightly divide it. Then we are to preach, rebuke, reprove, and exhort the Word.
Prov. 3:1-5
1
My son, forget not my law; but let thine heart keep my commandments:
2For length of days, and long life, and peace, shall they add to thee.
3Let not mercy and truth forsake thee: bind them about thy neck; write them upon the table of thine heart:
4So shalt thou find favour and good understanding in the sight of God and man.
5
Trust in the LORD with all thine heart; and lean not unto thine own understanding.
6In all thy ways acknowledge him, and he shall direct thy paths.
7Be not wise in thine own eyes: fear the LORD, and depart from evil.
We are to trust in the Lord for all our understanding and we are not to forget the laws but keep them in our hearts, which I believe the NT tells us that after Christ came that we are born with them already in our heart.
So to answer your question, no we aren't to rely on our own perceptions if they don't line up with scripture.
