Manipulation is deception. Manipualtion basically means:To manage/control in a skillfull way for ones own advantage.
Its selfish, motivated by carnality, and again, is deception. So is it right to EVER manipulate someone. No. i dotn think so.
However, sometimes we can manipulate others, and NOT know it, because WE are deceived, And we think we are jsut tryign to get them to understand, but instead we are goign OUTSIDE of GODs will, taking things into OUR hands, and controlling the siuation. Im not innocent in this,I have fallen into it. The Flesh LOVEs to manipulate.
Example(innocent one..but stil) A new accuaintance goes to shake your hand, You, being friendly(maybe even a bit attracted), instead of meeting her on the hand shake, go to hug her. She not wanting to hug you, but also not wanting to seem rude, participates in the hug. She doesnt really like it, but says nothing, and keeps a warm smile on. You don't see anything wrong with it. However, YOU just manipulated HER into hugging you, when she stated exacty what she wanted with the outstretched arm.
I know..a bit over the top, but thats the thing FLESH wants what it wants. No matter what. THAT is manipulation.
its Self(lots in the bible about that) and can be Deception(this too is all over the bible)
Well thats my two cents, Jesus bless you.
