The Christian's Secret of a Happy Life by Hannah Whitehall Smith

I remember loving this book when I came across it years ago. This morning, as I read parts of it from the Christian Classics Ethereal Library, I came across this:

"Having, therefore, taken the step of faith by which you have put yourself wholly and absolutely into His hands, you must now expect Him to begin to work. His way of accomplishing that which you have intrusted to Him may be different from your way. But He knows, and you must be satisfied.
I knew a lady who had entered into this life of faith with a great outpouring of the Spirit, and a wonderful flood of light and joy. She supposed, of course, this was a preparation for some great service, and expected to be put forth immediately into the Lord's harvest field. Instead of this, almost at once her husband lost all his money, and she was shut up in her own house, to attend to all sorts of domestic duties, with no time or strength left for any Gospel work at all. She accepted the discipline, and yielded herself up as heartily to sweep, and dust, and bake, and sew, as she would have done to preach, or pray or write for the Lord. And the result was that through this very training He made her into a vessel "meet for the Master's use, and prepared unto every good work."
Another lady, who had entered this life of faith under similar circumstances of wondrous blessing, and who also expected to be sent out to do some great work, was shut up with two peevish invalid nieces, to nurse, and humor, and amuse them all day long. Unlike the first lady, this one did not accept the training, but chafed and fretted, and finally rebelled, lost all her blessing, and went back into a state of sad coldness and misery. She had understood her part of trusting to begin with, but not understanding the divine process of accomplishing that for which she had trusted, she took herself out of the hands of the Heavenly Potter, and the vessel was marred on the wheel.
I believe many a vessel has been similarly marred by a want of understanding these things. The maturity of Christian experience cannot be reached in a moment, but is the result of the work of God's Holy Spirit, who, by His energizing and transforming power, causes us to grow up into Christ in all things. And we cannot hope to reach this maturity in any other way than by yielding ourselves up utterly and willingly to His mighty working. But the sanctification the Scriptures urge as a present experience upon all believers does not consist in maturity of growth, but in purity of heart, and this may be as complete in the babe in Christ as in the veteran believer."

Trust. Believe. Yield.

These passages illustrate why we are to praise God in all circumstances.

Rejoice evermore
Pray without ceasing
In everything give thanks: for it is the will of God in Christ Jesus concerning you.
I Thessalonians 5:16-18
