Jeremiah 17:9 The heart is deceitful above all things, And desperately wicked; Who can know it?
Where does the worshipping of idols come from? Where does the pride come from? Where does greed stem from?
They all start in our hearts. They start out as a little sparkle or a tiny idea and grow into something that takes over our hearts before we know it!
We don’t often see the fault until after it has all gone wrong, until we have hurt others and ourselves.
If you need to trust anything then trust in the Word of God because it is a sure thing, unlike our hearts.
