The beauty of gold catches the eye. Gold in its purest form is 24 karat. It has had all the impurities burned off and is very soft and pliable. It takes time and fire to refine gold to the point of purity, but once the process is complete, it is dazzling. It is the process of refining that we must go through to burn off our old ways and habits to make us pliable in the hands of God. You may be going through testing now and feel the burn of that refiner's fire, but remain steady and allow Him to bring out your beauty and change you. This time of testing strengthens your faith but requires you to rely solely on God for everything, submitting to Him just as the gold submits to the power of the goldsmith who works out every bit of dross bringing it to its purest form. As Christians, our purest form is Jesus. Our refining is burning off our old fleshly selves to reveal our true beauty, Jesus.
In this you rejoice, though now for a little while, if necessary, you have been grieved by various trials, so that the tested genuineness of your faith—more precious than gold that perishes though it is tested by fire—may be found to result in praise and glory and honor at the revelation of Jesus Christ. 1 Peter 1:6-7
