Separation and fire...

Separation, being set apart, it brings about the anointing, because anointing actually is separation.
Separation sustains the fire of God in your life because separation is anointing, and anointing is synonymous with oil, oil is needed to keep the fire burning. Exodus 27:20 " and thou shalt command the children of Israel, that they bring the pure oil olive beaten for the light, to cause the lamp to burn always ".
