Charles Spurgeon Commentary James 1:10-12

"and the rich, in that he is made low: because as the flower of the grass he shall pass away. For the sun ariseth with the scorching wind, and withereth the grass: and the flower thereof falleth, and the grace of the fashion of it perisheth: so also shall the rich man fade away in his goings. Blessed is the man that endureth temptation; for when he hath been approved, he shall receive the crown of life, which [the Lord] promised to them that love him." — James 1:10-12 (ASV)

Because as the flower of the grass he shall pass away. For the sun is no sooner risen with a burning heat, but it withereth the grass, and the flower thereof falleth, and the grace of the fashion of it perisheth: so also shall the rich man fade away in his ways.

Blessed is the man that endureth temptation:

Or, "endureth trial." Blessed is the man who is tried and tested, and who lives through it; who conquers, notwithstanding all the battle and struggle through which he passes. We should say, "Blessed is the man who is not tried;" but it is not so. He who, bearing the heavy load, receives gracious strength to sustain him under it, gets a greater blessing than the man who escapes the burden.
