For this cause also thank we God without ceasing, because, when ye received the word of God which ye heard of us, ye received it not as the word of men, but as it is in truth, the word of God, which effectually worketh also in you that believe.” 1 Thessalonians 2:13 (KJV)
In recent years there have been many in the political realm who claim that the Constitution of the United States is a “living document”. My understanding of their meaning is that the document is always changing with the culture and the times, which I believe to be completely false.
There is only one Living document which has been given to man, and that is the Word of God, with 66 books we call the Bible. When we speak of the Bible as a living document we do not mean that it is always changing with the times and/or culture. We mean that it lives to make changes in the people whose lives God touches in and through His Word.
In the above verse of the Bible the people of Thessalonica received the message of God’s Word from Paul, as though it came from God Himself; and Paul the apostle noticed that it was a powerful, living word; because he saw change in the people.
The author of Hebrews says, “The Word of God is quick [living] and powerful…” (Hebrews 4:12) and it surely is.
