The greatest difficulty while attempting to read and study the word of God is, allowing ourselves to be led of the Holy Spirit into all understanding, rather than being led by the teachings of others, which are froth with assumption, prejudice, supposition, and tradition which leads into error.
The people being taught by the Scribes, and Pharisee were led further and further away from God and His teachings, where it was said by Jesus, they would both fall into the ditch.
The same is true today, if the voice being heard, comes from the Teachings and the Doctrines of man.
Listen rather for the voice of God.
And ye shall know the truth, and the truth shall make you free.
