Psalm 12:6 The words of the Lord are pure words, Like silver tried in a furnace of earth, Purified seven times.
Have you ever tried to purify or change something by applying heat to it? Simple things like making jam or fudge rely on a lot of heat being applied at the right amount to change the food being cooked.
Too much heat and the food will get burned. Too little heat and it will not change into what you are trying to make.
God has supplied us with just the right amount in our Bibles for us to get to know Him in the right way. Not too much that we get drowned in details and not too little that we lose sight of Him.
Think about how He could do that for the same words to be just right for so many people all around the world…
