"Every word of God is pure; He is a shield to those who put their trust in Him. Do not add to His words, lest He rebuke you, and you be found a liar" (Proverbs 30:5-6).
As an assayer tests the purity of silver and gold, God's word stands the test of purity. It has been tried in the crucible of conflict, rebellion, rejection, and alienation by men. With the word of God, His people have weathered every storm of attack from faithless foes. His word continues to stand, while its adversaries lie in the ash heap of history. Undaunted, men and women of faith trust in the word of God, and are delivered. That is why they dare not add to it or take away from it. It does its work as it stands, undefiled and incorruptible. We shall never be persuaded that God's word is out of date - far from it. It is living and active, powerful and pure. God's word is able to save the lost and protect the saved. It is indeed "a shield to those who put their trust in Him." Respect it, believe it, obey it. To do less will bring God's rebuke upon those who simply pretend to trust Him.
