As Our Heavenly Father is judging the House of Eli, HE differentiates between the heart and the mind:
1Samuel 2:35 And I will raise me up a faithful priest, [that] shall do according to [that] which [is] in mine heart and in my mind: and I will build him a sure house; and he shall walk before mine anointed for ever. KJV
This is a critical differentiation. People tend to make decisions based on their mind or logic. The assumption is that if you feed the mind enough facts, it will bring forth the right solution. However, this is only partially true. Yes, at low levels of cause and effect you can adequately respond to issues at hand. If you want to grow vegetables, you can read books that explain the cause and effect of growing plants, buy the appropriate supplies, follow directions, and be successful. However, high impact life decisions require wisdom and understanding and these come from above (Daniel 1:17).
The mind has difficulty embracing infinity, the heart doesn’t. The “heart” is your essence, your soul. The mind is simply a servant to your essence. Our Heavenly Father distinguished the two aspects in the above Scripture, we should also embrace the difference. The more you feed your mind, the stronger it is. The same is true of your heart. Your heart may become weak:
Ezekiel 16:30 How weak is thine heart, saith the Lord GOD, seeing thou doest all these [things], the work of an imperious whorish woman; KJV
You may be “weak” in faith:
Romans 14:1 Him that is weak in the faith receive ye, [but] not to doubtful disputations. KJV
With improvements in technology, scientists are now able to detect communications of the heart to the rest of the body. It has a separate and distinct intelligence from the brain. The communication system of the body is much more complex than we have been taught in the past.
The challenge we face is to change our focus from “head” knowledge to “heart” knowledge. The world uses noise to keep that focus from occurring. To listen to the still small voice is difficult when the focus is elsewhere. Our minds would have us seek volumes of information and contraptions for answers when our answer is only a whisper away.
