James 1:22-25 (New Living Translation)

But don’t just listen to God’s word.

You must do what it says.
Otherwise, you are only fooling yourselves. 

For if you listen to the word and don’t obey,
it is like glancing at your face in a mirror. 
You see yourself, walk away,
and forget what you look like.

 

But if you look carefully into the
perfect law that sets you free,
and if you do what it says and
don’t forget what you heard,
then God will bless you for doing it.

In the natural, the spirit realm can’t be seen or felt, the only way to accurately perceive spiritual truth is through the Bible. Simply take God’s Word and believe it!

Jesus said in John 6:63,

“It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.”

God’s Word reveals spiritual reality. If you want to know what your spirit is like, you must find out from the Word, not relying on emotions or other perceptions. God’s Word is spirit and life! It’s the reflection of who you really are.

When you look at your face in a mirror, you aren’t really seeing yourself, you’re viewing a reflection. Even though it’s only a reflection, you have learned to trust it and act on what you see.
 
God’s Word is just like that mirror; it reflects perfectly who you are in the spirit.
