Jeremiah 17:9-10
The heart is deceitful above all things and beyond cure. Who can understand it? "I the LORD search the heart and examine the mind, to reward a man according to his conduct, according to what his deeds deserve."

What will we do if have some gadget giving trouble and we don't know much about that gadget? We would take help from someone who knows about the gadget. It is better to give it to them rather than trying to find it ourselves and repair it. This will save our money and time.

The word "beyond" in the above scripture can mean that it is impossible. Unless you understand something it is not possible to repair it or make changes to it.

God alone is the technician of all hearts. It is better to surrender our heart to Him. Sometimes trying to mend it ourselves will only end up in more damage.

He is the potter and we are the clay. Are we being a easily moldable clay?

Application

Think about situations in life that you could see how your heart has decieved you. Thank God for helping during those times to rely on him.
