'Knowledge' in the Bible

and [that you are] a corrector of the foolish, a teacher of the [spiritually] childish, having in the Law the embodiment of knowledge and of the truth—

For I testify about them that they have a certain enthusiasm for God, but not in accordance with [correct and vital] knowledge [about Him and His purposes].

Oh, the depth of the riches and wisdom and knowledge of God! How unsearchable are His judgments and decisions and how unfathomable and untraceable are His ways!

Personally I am convinced about you, my brothers and sisters, that you yourselves are full of goodness, amply filled with all [spiritual] knowledge, and competent to admonish and counsel and instruct one another.
