Two elements that makes fire are “wood” and “fuel.”
The word is wood while prayer is fuel.
When the two are combined, fire results on the altar.
It is the duty of the priest to generate the two.
The priest is custodian of the word (Leviticus 6:12,13 & 27) and an intercessor.
By the word, he feeds the people (Micah 6:9; 7.14) and by prayer, he keeps them warm, and Satan cannot survive a warm environment.
Jesus the high priest came to establish the order – He will pray at night and feed the people at daytime.
The apostles continued with the same principles – Acts 1:14-26; 6:4.
By feeding God’s people with the word, we get them stabilized and immovable by the enemy and by prayer we keep them warm and unreachable by the devil.
