Matthew 6:4

That thou appear not unto men to fast, but unto thy Father which is in secret: and thy Father, which seeth in secret, shall reward thee openly.

But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly.

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.

And thou shalt be blessed; for they cannot recompense thee: for thou shalt be recompensed at the resurrection of the just.

Shall not God search this out? for he knoweth the secrets of the heart.

Can any hide himself in secret places that I shall not see him? saith the LORD. Do not I fill heaven and earth? saith the LORD.

For nothing is secret, that shall not be made manifest; neither any thing hid, that shall not be known and come abroad.

Wherefore the LORD God of Israel saith, I said indeed that thy house, and the house of thy father, should walk before me for ever: but now the LORD saith, Be it far from me; for them that honour me I will honour, and they that despise me shall be lightly esteemed.

And whosoever shall give to drink unto one of these little ones a cup of cold water only in the name of a disciple, verily I say unto you, he shall in no wise lose his reward.

Therefore judge nothing before the time, until the Lord come, who both will bring to light the hidden things of darkness, and will make manifest the counsels of the hearts: and then shall every man have praise of God.

Yea, the darkness hideth not from thee; but the night shineth as the day: the darkness and the light are both alike to thee.

Now unto him that is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy,

Neither is there any creature that is not manifest in his sight: but all things are naked and opened unto the eyes of him with whom we have to do.

Thou hast proved mine heart; thou hast visited me in the night; thou hast tried me, and shalt find nothing; I am purposed that my mouth shall not transgress.

And I will kill her children with death; and all the churches shall know that I am he which searcheth the reins and hearts: and I will give unto every one of you according to your works.
