The omniscience and omnipresence of God is the topic of Proverbs 15:3.
Proverbs 15:3 – “The eyes [knowledge] of the LORD are in every place, beholding [watching; spying out] the evil [wicked] and the good [pleasing to the Lord; like pure gold].”
For the righteous, the reality that “the eyes of the Lord are in every place” (Prov. 15:3) is a comfort. Like a loving mother whose protective eye follows her toddler’s excursions from her shadow to the playground, God watches over the righteous providentially guiding and guarding their way (Genesis 24:27, 48; Psalm 37:23). Psalm 91, one of my favorite psalms, is rich with reminders of the omnipresence and omniscience of God: He is the Abiding place of the godly (Psalm 91:1), a Refuge and Fortress (Psalm 91:2, 9) and Deliverer (Psalm 91:3, 15). Our lives would be changed if we remembered God sees everything and hears every word!
What is a comfort to the righteous is a cause for dread and foreboding for the wicked. The assurance of God’s omnipresence and omniscience should strike fear in the heart of the wicked. Like Adam and Eve’s flight from the presence of God, some sinners attempt to flee from God’s presence (Genesis 3:8). Others, like Moses, seek to conceal their sin, forgetting that no act of sin goes unnoticed by God (Exodus 2:11-15). Some sin, foolishly believing God will forget their transgressions (Psalm 10:11).
Jesus taught His disciples “that every idle [useless] word that men shall speak, they shall give account thereof in the day of judgment. 37 For by thy words thou shalt be justified [declared innocent], and by thy words thou shalt be condemned [judged guilty]” (Matthew 12:36-37).
Psalm 139:1-6 – “O LORD, thou hast searched me, and known me.
2 Thou knowest my downsitting and mine uprising, thou understandest my thought afar off.
3 Thou compassest my path and my lying down, and art acquainted with all my ways.
4 For there is not a word in my tongue, but, lo, O LORD, thou knowest it altogether.
5 Thou hast beset me behind and before, and laid thine hand upon me.
6 Such knowledge is too wonderful for me; it is high, I cannot attain unto it.”
