Amen Robbie!
It is amazing how we can fool ourselves! People will come telling us we can't trust ourselves, and yet they trust that WE can interpret the Bible.
The key is Christ, and I would say that includes putting on his character; if we remain humble and broken, looking to God and trusting in him, he will not betray us or let us down! The Almighty God will come to the rescue of those who look to Him with a contrite heart.
THAT is how you don't trust yourself, but rather trust the Lord.
If we say we trust a book, ink and paper, we really just trust OURSELVES with the book, and our interpretation of it. We must completely deny our selves and in all humility surrender ourselves to Christ for his leading. Then he will indeed open our understanding to the scriptures!
Our eyes are to be on Him!
