God’s Word is intended by Him to reveal His character, will, plan and purpose to us. It was not written to conceal Him or what He intends for man.
29“The secret things belong to the Lord our God, but the things revealed belong to us and to our sons forever, that we may observe all the words of this law. (Deuteronomy 29:29 NASB95)
13For behold, He who forms mountains and creates the wind And declares to man what are His thoughts, He who makes dawn into darkness And treads on the high places of the earth, The Lord God of hosts is His name. (Amos 4:13 NASB95)
It would be somewhat nonsensical for Him to cause His words to be recorded, and no one could figure them out. God lets us in on what He is doing and will do, and what He expects from man. We have no excuse to be ignorant of what God requires. The Bible is preserved for us so that we can read it and learn about God. He made sure the words were written down so other generations would have information they could use to find Him.
16“Come near to Me, listen to this: From the first I have not spoken in secret, From the time it took place, I was there. And now the Lord God has sent Me, and His Spirit.” 17Thus says the Lord, your Redeemer, the Holy One of Israel, “I am the Lord your God, who teaches you to profit, Who leads you in the way you should go. 18“If only you had paid attention to My commandments! Then your well-being would have been like a river, And your righteousness like the waves of the sea. (Isaiah 48:16-18 NASB95)
7Surely the Lord God does nothing Unless He reveals His secret counsel To His servants the prophets. (Amos 3:7 NASB95)
One of the big reasons that the Reformation was so effective is that the Bible was translated into common languages. Everyone could compare the existing church with the one in the book of Acts. They didn’t match up too well, and reform was demanded. God meant the Bible to be understood, and to reveal His works and character and power to all generations, at least to those of the generations searching for Him.
