What does God know? One of the core attributes of God is that he is omniscient. What that means is that God knows everything. In 1 John, John wrote about love being the mark of the Christian and how the presence of love can reassure us that we are really saved. Then he said this: “For whenever our heart condemns us, God is greater than our heart, and he knows everything. But God doesn’t know things the way you and I know things. Everything that you know, there was a time when you didn’t know it. You learned it. Someone taught you, or you observed it or you figured it out. God doesn’t learn. There’s never a time when God doesn’t know something and comes to know it. He simply knows everything.
