How do we know God's infinite knowledge is true?

God's infinite knowledge is foundational to our understanding of His sovereignty. In 1 Samuel 23, we see that God not only knows what will happen but also understands all potential outcomes. This is a demonstration of His omniscience, as He provided David with insights into Saul's actions and the loyalty of the inhabitants of Keilah. Psalm 139 echoes this truth, stating that God understands our thoughts and actions fully. Such knowledge is beyond human comprehension, reaffirming our reliance on Him.
