Aggression

all that enter in to perform the service to do the work in the tabernacle of the congregation.  Numbers 4:23b, KJV.

The Hebrew word for "perform" is Tsaba'.  It literally means to wage war, fight, or to go forth to war.
It turns out that the Gershonites were rather aggressive!
Whenever we are serving in our capacity to minister the gospel it is an act of warfare against the kingdom of this world.  In response the prince of the power of the air (Eph 2:2) seeks to hinder the kingdom of God from advancing.  Opposition occurs.  There is a battle that takes place in the invisible, before results can be experienced in the visible.  
This is why Paul told Timothy,"This charge I commit unto thee, son Timothy, according to the prophecies which went before on thee, that thou by them mightest war a good warfare;  1 Timothy 1:18, KJV.
Many people take their stand at Elevation Church on the weekend.  Some people say that it is not about the numbers, but it is very much about the numbers because there is power in the simple act of agreement.  As a matter of fact it's getting harder and harder to disagree that there is definitely something going on at Elevation Church that is, "NOT NORMAL."
