DON'T Deceive Your Soul!

In James 1:23, we learn that the word of Truth is for "obeying". And if anyone hears the Word and does not obey it, he is like a man who looks at his own face in a mirror, and after that mirror is removed, he forgets what kind of person he really is.

The notion here is we frequently take notice of ourselves in a mirrors reflection. When we do, we can see all the blemishes and even our countenance. Some will identify the need for improvement and/or things they should to do to change. And we are affected by our own appearance; positive or negative. 

After the mirror is removed, we soon forget what manner of person we really are, because we no longer see our face reflected. We don't recollect how disagreeable we appeared, and our own resolutions of improving our countenance. 

The doctrines of God, faithfully preached, are such a mirror; he who hears cannot help discovering his own character, and being affected with his own deformity. He sorrows, and purposes amendment; but when the preaching is over, the mirror is removed. Not being careful to examine the records of his salvation, the perfect law of liberty (James 1:25) or not continuing to look therein, he soon forgets what manner of man he was; or, reposing some unscriptural trust in God's mercy, he reasons himself out of the necessity of repentance and amendment of life, and thus deceives his soul. Adam Clarke's Commentary.

Be careful to examine!
So everyone who hears these words of Mine and acts upon them [obeying them] will be like a sensible (prudent, practical, wise) man who built his house upon the rock. Matthew 7:24
