Wherefore let him that thinketh he standeth take heed lest he fall. – 1 Corinthians 10:12

If there were no temptation from without, you are fickle enough in yourself. Ah! we might sooner trust the wind or rely upon the glassy waves of the ocean than trust our own frail resolutions. We are changeable, we are false; our hearts are deceitful above all things, and desperately wicked. Let him that putteth on his harness take care not to boast as him that putteth it off. There are dangers ahead and many trials. All is not gold that glitters. Firm resolutions are not always kept; yea, let me add they are never kept if they are made in your own strength; they will go most surely, and you that promised to stand fast will soon turn aside.

There will be, with some of you, the jeers and sneers of those you work with. They will call you ill names. Perhaps they have began it already. Well that you do not know what they can invent! The Christian soldier has a gauntlet to run. The Christian worker in many a large factory has to endure a lifelong martyrdom. Men will invent all sorts of gibes and jeers against a believer in Christ, and it is a fine sport to pelt a Christian. Can ye cleave to your Lord then? Oh! if you cannot, you do not know Him, for He is worth ten thousand times ten thousand sneers, and you should count it a joy to be permitted to bear a scoff for Him. Now are you in your measure partakers with the noble host of martyrs. You cannot in these softer days earn the ruby crown of martyrdom, but you have, at least, the trial of cruel mockings. Bear up manfully, and meet their mockery with your holy bravery and patient endurance.~ C.H. Spurgeon
