Deuteronomy 27:26 Cursed be he that confirmeth not all the words of this law to do them. And all the people shall say, Amen.
God’s people were required to acknowledge the Word and Words of God. They had to say publicly that they knew it was God saying it and that they would accept it as such.
As you read this passage you realize that what God said was the authority. They were acknowledging that in this verse.
Today, we are not required to acknowledge that the Bible is God’s Word but it is. We may not hear that we are cursed if we do not acknowledge it but in all reality those that will not recognize the Bible as God’s Word will die and go to Hell.
God’s Word is the only way we know the truth. It is the only way we know God.
