"The heart is deceitful above all things, and desperately wicked: who can know it? I the LORD search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings."
There have been comments on the "heart" and we can suffice to say it is the very core of our thinking, containing what we hold as true. If you believe in Jesus Christ as your Savior, this is where He abides. The Lord will search the heart to not only see if Jesus abides there, but also what you KNOW of Him as well as the principles, promises, doctrines, precepts and techniques found in His Holy Word.
He will test you...by trying the "reins". These are not the reins as found on a horse to guide. No, these reins deal with the kidneys. [check Strawn's] Above each of the kidneys are the adrenal glands, which give us fight, flight, or fright. The emotions. There is no thought in the emotions, only in the mentality (see "heart" above.)
Your emotions will deceive you. Often when people refer to the heart, following it, etc., they are confusing it with the emotions because they think of the Biblical heart as being that pump in our chest that beats rapidly when the emotions kick in. This is serious error. Biblically, the heart is the seat of our thinking and is in our head. By confusing the two, many set themselves up for a colossal fall. When the emotions kick in, the mentality shuts down.
Emotions will convince you to buy a Corvette when you need a minivan. Emotions will have you curse the spouse you dearly love in the heat of an argument. Emotions will have you beat your children for misbehavior when a light spanking or even a sit down talk would do much, much better.
There is nothing wrong with emotions, unless they override the mentality. The emotions are the "appreciator" of the soul. The emotions are to respond to the mentality, never should they have dominion over it.
If there is a decision to be made and the emotions are piquing to the point of usurping the mentality, that is the time to take a walk, take a shower, take a nap...whatever it takes to calm them down. You cannot think rationally until the emotions are put in check and in all likelihood will make a wrong decision if you do not.
I pray I have helped someone today, in Jesus' Name. Amen.
Have a Blessed Day!
