God's thoughts, personality, and attitudes can only be known if God chooses to reveal them. All else would be human speculation. We are at a loss if God does not wish to be known. But God wants us to know Him and has told us in the Bible all we need to know about His character and how to relate to Him. This makes the reliability of the Bible an important consideration.
Archaeological findings continue to confirm the accuracy of the Bible, rather than refute it.
The Dead Sea Scrolls and other archaeological discoveries continue to substantiate the historical accuracy of the Bible. Yet there is an astounding consistency in its message. He deeply loves us. He is holy and therefore cannot be in relationship with sinful people. But God provided a way for our sins to be forgiven.
