This phase is often applied to a situation when a person becomes unable to stand, and/or loses consciousness and collapses and/or lays on the ground, a chair, or whatever is under them when they leave their feet. It sometimes occurs (but not always) during or after some of the activities below:
a) Being in the presence of the Holy Spirit
b) Being in the presence of a person in whom the Holy Spirit’s presence is strong
c) Having had hands laid on them during prayer and/or spiritual declaration
d) Simply being prayed for, without being touched by human hands
e) Being under the sound of voice of someone operating in a powerful anointing of the Holy Spirit.
“Out under the Power” refers to the effect of the presence of the Holy Spirit and his power on a person; the effect being unable to stand or unconscious (out) in the presence of this power. Sometimes they are aware of everything that is happening around them; sometimes they are able to talk and interact with others; and sometimes they are unaware of what is going on outside their communion with the Holy Spirit. Another phase often used to describe this situation is “Slain in the spirit”; referring to the effect of the Holy Spirit’s power on a person’s spirit and body. Both phrases are used interchangeably.
Is there any biblical documentation of this activity? Yes:
a) Matthew 18:3-6 – Jesus, obvious being full of the Holy Spirit had this effect of the guards sent to capture him. They collapse to the ground in the presence of his power.
b) Acts 9:1-4 – Paul was knocked down by the power of the Lord while he was traveling to Damascus.
c) Daniel 10:4-10 – Daniel finds himself in the presence of an angel of the Lord and the effect on him was to lose the ability to stand (“…there remained no strength in me: for my comeliness was turned in me into corruption and I retained no strength”). He had to be helped on to his knees by the angel
This effect sometimes counterfeited when leaders and ministers try to produce it by extreme volume on microphones, yelling at people and then pushing them over when they “laid hands” on their heads or chests (sometimes even hitting them).
You must understand that collapsing to the ground when having hands laid on you is not required and does not prove or certify anything. If you are unable to stand when someone lays hands on you (they are not pushing you off balance in some way) , and/or you find yourself in the presence of the Holy Spirit, or a declaration is made to you in the power and anointing of the Holy Spirit, then it is not out of order to fall to the floor – if you can’t stand, you can’t stand.
