A 'language of the heart'?

Here is an interesting blog post written by a Linguistics colleague. What is a 'language of the heart'? Is it important to be able to read the Bible in the 'language of the heart'? Certainly, it's important to be able to read (or hear) it in a language you can understand. The language of the Bible (whatever that may be) will then speak to your heart through the work of the Holy Spirit (cf. Ezekiel 2:1-3, 1 Corinthians 2:6-16).
