New Life Version
23 Anyone who hears the Word of God and does not obey is like a man looking at his face in a mirror. 24 After he sees himself and goes away, he forgets what he looks like. 25 But the one who keeps looking into God’s perfect Law and does not forget it will do what it says and be happy as he does it. God’s Word makes men free.
In our crazy world, the message is to make yourself happy, look out for number one, do what feels right, be who you are, find yourself, etc. These attitudes can even invade our churches - they are made up of people, after all.
But the scripture referenced indicates that it is not about ourselves. In fact, if you are "finding" yourself outside of the mirror of God's Word, you will be unhappy. We need to use the Word of God as a mirror into our lives - find yourself in the Word let it change you - and be happy and free!
