Such lessons are sometimes hard for a man of James’s passions to learn. But if I have to choose between a man of burning, flaming, passionate, enthusiasm with a potential for failure on the one hand, and a cold compromiser on the other hand, I’ll take the man with passion every time. Such zeal must always be harnessed and tempered with love. But if it is surrendered to the control of the Holy Spirit and blended with patience and longsuffering, such zeal is a marvelous instrument in the hands of God. The life of James offers clear proof of that.
