It is because He loves us so much that He tries us by delaying His answers of peace…Love closes the hand of divine bounty and restrains the outflow of favor when it sees that a solid gain will ensue from a period of trial…Who would desire to see the gold taken out of the fire before its waste is consumed? Wait, O precious thing, until you have gained the utmost of purity! These furnace moments when you are in the hands of God are profitable. It would be unwise to shorten such golden hours. The time of the promise corresponds with the time most enriching to the heart and soul.
Charles Spurgeon, from the book “God Promises You” as quoted by Tim Burns in the Bible study titled, “Forged in The Fire”.
But He knows the way that I take; When He has tested me, I shall come forth as gold. Job 23:10
That the genuineness of your faith, being much more precious than gold that perishes, though it is tested by fire, may be found to praise, honor, and glory at the revelation of Jesus Christ. 1 Peter 1:7
But let patience have its perfect work, that you may be perfect and complete, lacking nothing.
