II. Note, again, the testing of the wealth.
I need not dwell upon that very familiar metaphor of the furnace for gold, and the fining-pot for silver, only remember that there are two purposes for which metallurgists apply fire to metals. The one is to test them, and the other is to cleanse them, or, to use technical words, one is for the purpose of assaying them, and the other is for the purpose of refining them. And so, linking the words of my text with the words of the previous verse, we find that the Apostle lays it down that the purpose of all the diverse trials, or 'temptations' as he calls them, that come to us, is this one thing, that our faith should be 'tried,' and 'found, unto praise and honour and glory.' The fire carries away the dross; it makes the pure metal glow in its lustre. It burns up the 'wood, hay, stubble'; it makes the gold gleam and the precious stones coruscate and flash.
And so note this general notion here of the intention of all life's various aspects being to test character is specialised into this, that it is meant to test faith, first of all. Of course it is meant to test many other things. A man's whole character is tested by the experiences of his daily life, all that is good and all that is evil in him, and we might speak about the effect of life's discipline upon a great many different sides of our nature. But here the whole stress is put upon the effect of life in testing and clarifying and strengthening one part of a Christian's character, and that is his faith. Why does Peter pick out faith? Why does he not say 'trial of your hope,' of your 'love,' of your 'courage,' of half a dozen other graces? Why 'the trial of your _faith_?' For this reason, because as the man's faith is, so is the man. Because faith is the tap-root, in the view of the New Testament, of all that is good and strong and noble in humanity. Because if you strengthen a man's trust you strengthen everything that comes from it. Reinforce the centre and all is reinforced. Your faith is the vital point from which your whole life as Christians is developed, and whatever strengthens that strengthens you. And, therefore, although everything that befalls you calls for the exercise of, and therefore tests, and therefore, rightly undergone, strengthens a great many various virtues and powers and beauties in a human character, the main good of it all is that it deepens, if the man is right, his simple trust in God manifested by his trust in and love to Jesus Christ: and so it reinforces the faith which works by love, and thus tends to make all things in life good and fair.
Now if thus the main end of life is to strengthen faith, let us remember that we have to give a wider meaning to the word 'trials' than 'afflictions.' Ah! there is as sharp a trial of my faith in prosperity as in any adversity. People say, 'It is easy to trust God when things are going well with us.' That is quite true. But it is a great deal easier to stop trusting God, or thinking about Him, when things are going well with us, and we do not seem to need Him so much, as in the hours of darkness. You remember the old story about the traveller, when the sun and the wind tried which could make him take off his cloak; and the sun did it. Some of us, I daresay, have found out that the faith which gripped God when we felt we needed Him, because we had not anything else but Him, is but too apt to lose hold of Him when fleeting delights and apparent treasures come and whisper invitations in our hearts. There are diseases that are proper to the northern, dark, ice-bound regions of the earth. Yes! and there are a great many more that belong to the tropics; as there is such a thing as sunstroke, which is, perhaps, as dangerous as the cramping cold from the icebergs of the north. Some of us should understand what that Scripture means: 'Because they have no changes, therefore they fear not God.' Prosperity, untroubled lives, lives even as the lives of those of the majority of mankind now, have their own most searching trials of faith.
