Psalm 119:140 Your word is very pure; Therefore Your servant loves it.
For something to be purified it has to endure trials. In order for steel to be made it has to endure the blast furnace, extreme temperatures and extreme conditions. In order for gold to be purified it has to endure lots of heat too.
God’s Word has endured so much over so many years that we can know it is true and pure, without corruptions, without man’s flaws.
We need to uphold that truth and live by it because it has been tried and tested. We need to love it and hold it close to our hearts. We need to trust in it wholly.
