During a deliverance, the spirit in this sister said that it would gain a lot of power if it took her to Hell. These spirits are not your friend. Be very careful of them. They want to take you to Hell for their own gain:
They came to use and then to destroy you:
Exodus 15:9 King James Version (KJV)
9 The enemy said, I will pursue, I will overtake, I will divide the spoil; my lust shall be satisfied upon them; I will draw my sword, my hand shall destroy them.
Do not have pity on them. Satan is the father of lies:
John 8:44 King James Version (KJV)
44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
Satan came to kill, Jesus came to give life:
John 10:10 King James Version (KJV)
10 The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly.
