That the trial of your faith, being much more precious than of gold that perisheth, though it be tried with fire, might be found unto praise and honour and glory at the appearing of Jesus Christ – 1 Peter 1:7

Your faith will be exercised. An untried faith will be no faith at all. God never gave men faith without intending to try it. Faith is received for the very purpose of endurance. Just as our Rifle Corps friends put up the target with the intention of shooting at it; so does God give faith with the intention of letting trials and troubles, and sin and Satan aim all their darts at it. When thou hast faith in Christ it is a great privilege; but recollect that it involves a great trial. You asked for great faith the other night; did you consider that you asked for great troubles too? You cannot have great faith to lay up and rust. Mr. Greatheart in John Bunyan’s The Pilgrim’s Progress was a very strong man, but then what strong work he had to do. He had to go with all those women and children many scores of times up to the celestial city and back again; he had to fight all the giants, and drive back all the lions; to slay the giant Slaygood, and knock down the Castle of Despair. If you have a great measure of faith, you will have need to use it all… But when your faith is exercised with trials, do not think you are brought into judgment for your sins. Oh no, believer, there is plenty of exercise, but that is not condemnation; there are many trials, but still we are justified; we may often be buffeted, but we are never accursed; we may ofttimes be cast down, but the sword of the Lord never can and never will smite us to the heart…If you are really resting in Christ, though your faith may be but as a spark, and a thousand devils may try to quench that one spark, yet you are not condemned-you shall stand accepted in Christ. ~ C.H. Spurgeon
