James 1:25

But the man who looks intently into the perfect law that gives freedom, and continues to do this, not forgetting what he has heard, but doing it—he will be blessed in what he does.
(NIV)

The opposite to the man who lives in self-deception is the man who looks into the word, and does what it says.

Notice that it says that this man is looking intently. That word intently means to stoop down in order to clearly see. This man is studying the word. He is desiring to have his heart revealed.

Notice also that he is not forgetting the word. He walks away and immediately puts it into action. His heart has been revealed and he knows that something needs to be done. He doesn't forget the word, it is in his heart.

Be a doer of the Word and not a hearer only.
