"Consider it pure joy, my brothers and sisters, whenever you face trials of many kinds, because you know that the testing of your faith produces perseverance. Let perseverance finish its work so that you may be mature and complete, not lacking anything." James 1:2-4 (NIV)
Testing is what silversmiths did. They would heat the silver and the impurities would rise to the top and they would discard them….and they did it again and again until they could see their reflection in the pure silver. With God testing/purifying us, He will hopefully see His own reflection in us.
Is the “testing of your faith” resulting in the reflection of God, or more impurities?
