Attribute: a characteristic or quality of a person or thing.

Webster's New World Collegiate Dictionary defines omniscient as: having infinite knowledge; knowing all things.

The Apostolate's Family Catechism says that God is all-knowing because He knows all things in the past, present, and future, as well as all potential things. God knows all things that are or ever could be. Everything is like one thought in the mind of God. ¹

• Why would we dwell on the fact that God is omniscient?
  
  
• Scripture tells us this truth over and over again and we need to know why this is important in our lives.
  
  
• Sir 42:18-20 ² - He searches out the abyss, and the hearts of men, and considers their crafty devices. For the Most High knows all that may be known, and he looks into the signs of the age. He declares what has been and what is to be, and he reveals the tracks of hidden things. No thought escapes him, and not one word is hidden from him.
