Not that I speak in respect of want: for I have learned, in whatsoever state I am, therewith to be content. Philippians 4:11.
Oh that we could be satisfied with less heart-longings, less striving for things difficult to obtain, ... while that which God values above jewels, the meek and quiet spirit, is not cherished.... It is better to endure cheerfully every inconvenience than to part with peace and contentment.—Testimonies for the Church 4:622.
There are restless ones who, were they to go to a new place to live, would still be dissatisfied, because the spirit of disaffection is in the hearts, and a change of place does not bring a change of heart. Their characters have not been refined and ennobled by the Spirit of Christ. They need to learn the lesson of contentment.—Fundamentals of Christian Education, 495.
Those who are drinking at the fountain of life will not, like the worldling, manifest a longing desire for change and pleasure. In their deportment and character will be seen the rest, and peace, and happiness that they have found in Jesus by daily laying their perplexities and burdens at His feet. They will show that there is contentment and even joy in the path of obedience and duty.—Testimonies for the Church 4:432.
