# Keep thy heart

## with all diligence: for out of it are the issues of life.

### Proverbs 4:23

#### Overview

This is a blog encouraging Christians to maintain godly standards of holy living in their lives. Because our hearts are such precious assets, they deserve to be kept from the pollution and moral filth of this ungodly world. A person's heart sends forth the "issues of life" like a fountain (Proverbs 4:23), and when it is pure, it is a beautiful thing.
