Many are those that may burn in passionate love for The Lord who sing his praises and cannot be straightened in their zeal for him confessing their fiery love for Him. Yet when it comes to that lonely step of faith of obedience that is met with the icy cold wind of resistance they halt and step back secretly in their heart all the while confessing His Name and His Word.
There are times when the Fire burns in our bosom and we cannot stay but speak and move. But that is the rare blessed exception. To live in awareness of that Flame and it's purifying work is to quench it. To focus on the Flame and not the Still Small Voice of The Word inside of it is to get distracted and be turned aside to the emotion and phenomenon of the Fire & not the command. Though the Burning Flame in the heart of the quickened saint may be a new experience - the Cross must have its deep crucifying affect and separate the emotional feeling of the soul from the burning sensation of the Spirit.
The "ministers of fire" described in Hebrews 1.7 are servants that are aflame but often feel very little as they take faith steps of obedience in great weakness. It is in this great weakness where the soul feeling is divided from the spirit that God is glorified the most and His power is revealed - otherwise if the servant serves in the awareness of the Powerful Burning he is strong in his soulish feeling and weak in his spirit to obedience. We follow, we obey for the utmost of reasons, because of Truth - that is living by "Every Word"
