James 1:3

3. Trying The putting to, or undergoing, the test.

Worketh The calling our spiritual and moral power into successful action increases the power, just as the muscle is hardened by exercise. Hence the perfectness of our Christian life is much the result of time, trial, and experience.

Patience Firmness against trial. The resisting the temptation and conquering the tempter begets hardihood and solidity. “The proof of the soldier is hard work, and not indulgence; the test of gold and silver is fire.”
