Here is Charles Spurgeon preaching on “the trial of faith”:
…who am I, and who are you, that God should pamper us? Would we have him put us in a glass case and shield us from the trials which are common to all the chosen seed? I ask no such portion. Let me fare as the saints fare. I only wish to have their bread and their water, and love their Father, and follow their Guide, and find their home. We will take our meals with them, whatever God puts upon the table for them, will we not? The trial of our faith will be all our own, and yet it will be in fellowship with all the family of grace.
It will be no child’s play to come under the divine tests. Our faith is not merely jingled on the counter like the shilling which the tradesman suspects, but it is tried with fire; for so it is written, “I have chosen thee in the furnace of affliction” (Isa 48:10). The blows of the flail of tribulation are not given in sport, but in awful earnest, as some of us know who have been chastened sore, almost unto death. The Lord tries the very life of our faith; not its beauty and its strength alone, but its very existence. The iron enters into the soul; the sharp medicine searches the inmost parts of the belly; the man’s real self is made to endure the trial. It is easy to talk of being tried, but it is by no means so simple a matter to endure the ordeal.
…”Oh,” you have said, “I wish I had more faith.” Your prayer will be heard through your having more trial. Often in our prayers we have sought for a stronger faith to look within the veil. The way to stronger faith usually lies along the rough pathway of sorrow. Only as faith is contested will faith be confirmed. I do not know whether my experience is that of all God’s people; but I am afraid that all the grace that I have got out of my comfortable and easy times and happy hours, might almost lie on a penny. But the good that I have received from my sorrows, and pains, and griefs, is altogether incalculable. What do I not owe to the hammer and the anvil, the fire and the file? What do I not owe to the crucible and the furnace, the bellows that have blown up the coals, and the hand which has thrust me into the heat? Affliction is the best bit of furniture in my house. It is the best book in a minister’s library. We may wisely rejoice in tribulation, because it worketh patience, and patience experience, and experience hope; and by that way are exceedingly enriched, and our faith grows strong.
…when affliction comes into the soul, and makes a disturbance and breaks our peace, up rise our graces. Faith comes out of its hiding, and love leaps from its secret place.
[“The Trial of Your Faith,” in 12 Sermons for the Troubled and Tried, Baker Book House, 1975, pp. 12-13]
I love that last line: “Faith comes out of its hiding, and love leaps from its secret place.”
