Jude 4:1

For certain people have crept in unnoticed. They are ungodly persons whose condemnation was predicted long ago, for the distort the grace of our God into decadence and immoral freedom and deny and disown our only Master and Lord, Jesus Christ.  

Our study of the bible is essential because it aids our power of discernment in biblical teaching. Suppose we get a check in our Spirit that something doesn’t line up with the word of God then research the word. We are responsible for keeping our hearts safe from false teachings and doctrines.
