How Do You Know? A systematic examination of the Biblical Doctrine of Knowledge. 1. We have general knowledge because every fact is a God-determined fact. 2. Apart from Christ, true knowledge is impossible, because all the treasures of wisdom and knowledge are hidden in Christ. 3. All humanity knows God, not all savingly, but they all know that He is. 4. Unbelief, therefore, is a willful ignorance and suppression of the truth. 1 Corinthians 1:18-25; 1 Samuel 2:3.
