What does the Bible say about God's word being perfect?

Psalm 18:30 states, 'As for God, his way is perfect; the word of the Lord is tried.' This teaches us that God's word is not only trustworthy but has also been refined through trials, similar to how metals are purified in a crucible. The concept of God's word being 'acrisolada' denotes its purity and reliability, signifying that it has faced challenges and emerged even stronger. This understanding is reinforced in other scriptures, such as Psalm 12:6, which claims that the words of the Lord are pure words, like silver refined in a furnace, purified seven times. Thus, believers can confidently trust the Scriptures as an infallible guide for their lives.
