What does the Bible say about gold tried in the fire?

In Revelation 3:18, Jesus counsels believers to buy from Him 'gold tried in the fire' symbolizing true faith that has been tested and refined. This spiritual gold represents the invaluable treasure of faith that endures trials and tribulations, akin to precious metals purged of impurities. As stated in 1 Peter 1:7, this faith is described as being 'more precious than gold that perisheth, though it be tried with fire.' The faithful who possess this enduring faith enjoy the promise of God's blessings and inherit eternal riches, surpassing all earthly possessions.
