God's Word in Your Heart

You will not find God's word in your heart unless you have put it there: 
Ps 119:11 Thy word have I hid in mine heart, that I might not sin against thee.

The word is put in your heart by reading, meditating, asking God for the 
Holy Spirit to give you understanding. James 3:17, 18. 

The word is sown in the heart from without, for even the field of the 
good heart does not have good seed until it is sown there by the Sower. 

Pleading inability to understand is no excuse, for that is your fault, 
and no one understands unless he cries out for understanding and wisdom. 
But God's word makes wise the simple and give understanding to the fool. 
But you must seek her as for hidden treasure.

God has words that you MUST receive from without. 
You will not find them in your heart which is a den of iniquity and lies:

1 My son, if thou wilt receive my words, and hide my commandments with thee;
2 So that thou incline thine ear unto wisdom, and apply thine heart to understanding;
3 Yea, if thou criest after knowledge, and liftest up thy voice for understanding;
4 If thou seekest her as silver, and searchest for her as for hid treasures;
5 Then shalt thou understand the fear of the LORD, and find the knowledge of God.
6 For the LORD giveth wisdom: out of his mouth cometh knowledge and understanding.

You will have no wisdom to speak in your mouth if you have 
not hidden it in your heart. Ps 119:27 Make me to understand the way of thy precepts: 
so shall I talk of thy wondrous works
