We hear so many pleas to please have a heart. So, how can the heart be where good comes from, and at the same time have the opposite claim?

Jeremiah 17:9  The heart is deceitful above all things, and desperately wicked: who can know it?

There is a similarity between our tongue and our heart. When speaking of our heart, we can be speaking of the physical heart or the emotional center ...which is actually the mind.  I am comparing the tongue and the emotional center of the mind.

The Bible says we have to bridle our tongue ...and I believe that we also have to bridle our heart, or emotional center.  Our emotions often have triggers ...our impulsive immediate reactions.  And these emotions are trained, and often manipulated.

The Bible says to train up a child in the way that he will go. Once trained, that child will have to find his way in the world ...and as more responsibility is expected, more independence is necessitated.

The difference between obtaining knowledge and experience ...is that experience grounds knowledge, and often defines it.  If someone allows minimal and solely personal experience to usher in judgment, then experience can skew points of view.  Experience can enhance our knowledge ...but without looking to the guidance of God, wisdom will be lacking.

So, with wisdom ...we bridle our heart, as well as our tongue.  This way, we save ourselves a lot of trouble ...and make the world a better place for others also.
