"This Bible sign has a dual application. "running to and fro and knowledge increase" also applies to knowledge of Biblical truths (see Amos 8:12). During the "dark ages", for over 1000 years, knowledge of Biblical truths were surpressed by the Roman Catholic Church. But since the protestant reformation and breakaway from Rome, God's people have been running to and fro in His Word FREELY and knowledge about great Bible truths have been revealed. God now has an end time remnant church with the FULL gospel truth to take to the world before the end comes, which was needed to fulfill the sign about taking the true gospel message to the whole world. Which you will read about further down the page."
