The heart is a place of secrets...

O Thestorides, of the many things hidden from the knowledge of man, nothing is more unintelligible than the human heart.” 8

The secrets that may be buried with a human heart.

In mystery our soul abides.

The heart has its reasons which reason knoweth not.

The heart has reasons that reason cannot know.

The heart has its reasons which reason knows not.

Alas! is even love too weak To unlock the heart, and let it speak? Are even lovers powerless to reveal To one another what indeed they feel? I knew the mass of men conceal'd Their thoughts, for fear that if reveal'd They would by other men be met With blank indifference, or with blame reproved; I knew they lived and moved Trick'd in disguises, alien to the rest Of men, and alien to themselves — and yet The same heart beats in every human breast!

The heart has its reasons which reason knows nothing of... We know the truth not only by the reason, but by the heart.

But often, in the world’s most crowded streets,
But often, in the din of strife,
There rises an unspeakable desire
After the knowledge of our buried life;
A thirst to spend our fire and restless force
In tracking out our true, original course;
A longing to inquire
Into the mystery of this heart which beats
So wild, so deep in us — to know
Whence our lives come and where they go.

The heart has its reasons which reason knows not of.

Those whom [the Lord] teaches, are always increasing in knowledge, both of themselves and of him. The heart is deep, and, like Ezekiel's vision, presents so many chambers of imagery, one within another, that it requires time to get a considerable acquaintance with it, and we shall never know it thoroughly. It is now more than twenty-eight years since the Lord began to open mine to my own view; and from that time to this, almost every day has discovered to me something which until then was unobserved; and the farther I go, the more I seem convinced that I have entered but a little way. A person who travels in some parts of Derbyshire may easily be satisfied that the country is cavernous; but how large, how deep, how numerous the caverns may be, which are hidden from us by the surface of the ground, and what is contained in them — are questions which our most discerning inquirers cannot fully answer…
And if our own hearts are beyond our comprehension, how much more incomprehensible is the heart of Jesus! If sin abounds in us — grace and love superabound in him! His ways and thoughts are higher than ours, as the heavens are higher than the earth; his love has a height, and depth, and length, and breadth, which passes all knowledge! The riches of his grace are unsearchable riches! Eph. 3:8, Eph. 3:18, Eph. 3:19. All that we have received or can receive from him, or know of him in this life, compared with what he is in himself, or what he has for us — is but as the drop of a bucket — compared with the ocean; or a single ray of light — compared with the sun. The waters of the sanctuary flow to us at first almost ankle deep — so graciously does the Lord condescend to our weakness; but they rise as we advance, and constrain us to cry out, with the Apostle, O the depth! We find before us, as Dr. Watts beautifully expresses it,
A sea of love and grace unknown,
Without a bottom or a shore!

O, lonely tomb in Moab's land,
O, dark Bethpeor's hill,
Speak to these curious hearts of ours,
And teach them to be still!
God hath His mysteries of grace — Ways that we cannot tell;
He hides them deep, like the secret sleep, Of him He loved so well.

The human heart has hidden treasures, In secret kept, in silence sealed; The thoughts, the hopes, the dreams, the pleasures, Whose charms were broken if revealed.
