Mark 4:21 ¶ And he said unto them, Is a candle brought to be put under a bushel, or under a bed? and not to be set on a candlestick? 22 For there is nothing hid, which shall not be manifested; neither was any thing kept secret, but that it should come abroad.
This is a scary verse and it should be, particularly for a lot of “holy” Christians, although literally Jesus is referring to spreading the knowledge of Him and letting the world know about Him and His message.
Matthew 10:26 Fear them not therefore: for there is nothing covered, that shall not be revealed; and hid, that shall not be known. 27 What I tell you in darkness, that speak ye in light: and what ye hear in the ear, that preach ye upon the housetops.
But, just think about God’s knowledge of your “secret” thoughts, intents, and deeds.
1Corinthians 3:13 Every man’s work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man’s work of what sort it is.
First, the Christian must understand that he or she has the Spirit of God living inside them. He sees every cellular function and knows every thought and it is through Him that we have constant access to the throne of heaven. It is not necessary for God to look down from heaven, peering through the clouds and cupping his spirit hand over his spirit ear to hear us speak and think. He has this knowledge from inside of us through our spirit.
Proverbs 20:27 The spirit of man is the candle of the LORD, searching all the inward parts of the belly.
Psalm 44:21 Shall not God search this out? for he knoweth the secrets of the heart.
The time is coming;
Romans 2:16 In the day when God shall judge the secrets of men by Jesus Christ according to my gospel.
We have been told, as Christians, commanded even;
2Corinthians 10:5 Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ;
Not many people are prepared to have their thoughts and intentions judged. Not many at all. We have a Book that does that to us as we submit to it by reading and believing it.
Hebrews 4:12 For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
God also sees things on earth directly through appearances known as angels.
Isaiah 63:9 In all their affliction he was afflicted, and the angel of his presence saved them: in his love and in his pity he redeemed them; and he bare them, and carried them all the days of old.
Matthew 18:10 Take heed that ye despise not one of these little ones; for I say unto you, That in heaven their angels do always behold the face of my Father which is in heaven.
Churches have angels before God as well which is apparent by reading the first few chapters of Revelation. And, yes, God can also see from heaven as time and space are no barrier to Him as He is beyond time and space and their constraints.
Exodus 20:22 And the LORD said unto Moses, Thus thou shalt say unto the children of Israel, Ye have seen that I have talked with you from heaven.
Genesis 22:11 ¶ And the angel of the LORD called unto him out of heaven, and said, Abraham, Abraham: and he said, Here am I.
So, God has a number of ways He can see every deed and thought of mankind. Remember, also that God is not a part of His creation but separate from it. He is present everywhere and at all times in some way which is hard for us to fathom. There are no secrets; no secret thoughts, no secret deeds. You didn’t get away with it. You will answer for it now or later, but you will give an answer for what you have thought or done.
