Is God righteous? Yes! How is the righteousness of God revealed? From faith to faith. God gives you truth, then you believe that truth; then God give you more truth. The more you obey the light, the more light you get. The reason some of us don't understand the Bible more than we do is because we have not been living up to the light that God has already given us. If you want to understand the part of the Bible you don't understand, begin to obey the part you do understand and you'll understand what you didn't understand. Do you understand?
Ask God for faith that will reveal to you the hidden truths of His Word that are hard for you to understand right now.
