"See to it that no one takes you captive by philosophy and empty deceit, according to human tradition, according to the elemental spirits of the world, and not according to Christ." - Colossians 2:8 ESV
'Takes you captive' is sylagōgeō (Strong's G4812) and it is a verb that speaks about stealing people. Kidnap would work as a translation.
"For in him the whole fullness of deity dwells bodily, and you have been filled in him, who is the head of all rule and authority." - Colossians 2:9-10 ESV
"Philosophy' and 'Deity' are also Hapaxes words.
There is a force that wants to take us away but there is a divine kingdom that can give us a home. The Godhead was at home in Christ.
Here it says 'Filled in Him' but the Greek word (plēroō - Strong's G4137) means to make complete.
A kidnapping always leaves a gap or wound. People get torn away from things and have no closure. If that has happened in the past there is still a remedy because we have a home in God that is as complete as Chist is in His identity. He has no gaps in His relationships to the Father and the Spirit.
The cross was a momentary gap made to let us in. He will bear the scars of that day forever so that we can be completely accepted.
A kidnapped person is never truly a part of the system that stole them. Our rebirth make us family. We are adopted and born in at the same time.
