…In the world ye shall have tribulation: but be of good cheer; I have overcome the world. – John 16:33

When a Christian is richest in grace he is poorest in himself. The way to grow rich in grace is to feel your poverty. Whenever you think you have stored up a little strength, a little comfort, a little provision against a rainy day, you are pretty sure to have the trouble you bargained for, and to miss the resources you counted on. Estimate your true wealth before God by your entire dependence on Him. The more you have, the less you have, and the less you have, the more you have. When you have nothing at all in yourself, then Christ is all in all to you. The perpetual condition of every child of God in himself is that of a needy and a poor and a helpless one-on the high mountains with his Lord, rejoicing in His love, yet is he even there in himself less than nothing and vanity-still poor and needy.

There have been times when we felt this very powerfully, perhaps, very painfully. Has Satan ever beset you, my brethren, with his fierce temptations? No doubt many of you have had to feel the ferocity of his attacks. Perhaps, blasphemous thoughts have been injected into your mind-dark forebodings, such as these, “God has forsaken me.” Perhaps, he has said, “He has sinned himself out of the covenant-he is a castaway,” and your poor little faith has tried to hold on to Christ, but it seemed as if she must be driven from her hold. While others found it as you thought easy to get to heaven, you realised the truth of the text-“The righteous scarcely are saved.” You have had to fight for every inch of ground, and it seemed to you often as though you had not a spark of grace in you, not a ray of hope, and not so much as a single grain of the grace of God within your heart. Ah! and at such times you have been poor and needy, and you have had no helper. And, perhaps, at such seasons, too, temporal trouble may have come in. Whoever may go through the world without trouble, but God’s people never do.

“The path of sorrow, and that path alone,
Leads to the place where sorrow is unknown.”
