You are WRONG-big time! The brain is a muscle as well, but a greater muscle than the heart is woman!
What about your brain the seat of intelligence! You are ignorant! The heart is nothing compare to the brain.
God Spirit in not in my heart, it is in my brain. When God anointed me it wasn’t in my heart, it was in my brain. When God and I communicated back and forth it wasn’t from my heart, in was in my brain!
I have no doubt YOU LOVE GOD WITH YOUR BRAIN, but the brain is an organ AND not a muscle.
The scripture clearly tells you that the flesh and the heart fails, but that strength for the heart God makes strong. In this God be praised!
It is apparent that you have not understood the "discernment of the Spirit of God is Love. " If this is so, you will love with all Him with all your heart, body soul and spirit.
For many having thinking as you are still in darkness & have not received the Holy Spirit because they have not asked for it. I do not go against God who can speak both to the Spirit and the heart.
Flesh is the brain it fails, Mind is the Spirit it is God it will not fail.
All Power HAS GOD.: "I AM THE LORD, THE GOD OF ALL FLESH...IS THERE ANYTHING TOO HARD FOR ME?" --Jeremiah 32:27 KJV
Harry, it sound doctrine that you cannot place limitations on the possibilities of God. What you are refusing to accept is you cannot be taught anything; but that you know everything there is to know about God,
Let me teach you that you cannot know everything about God, God has no limitations of His power and that it is the acceptable FEAR to knowing Him WE GAIN HIS SPIRIT OF KNOWLEDGE, LOVE AND TRUTH.
God has said He searches the heart, AND God is clothed with strength even for the heart.
