(Colossians 2:8-10 NASB)
Why should we never ever let anyone take us captive with their philosophies and religious traditions?
Answer: because we are already made complete in the One in whom the fullness of God dwells bodily.
In other words, Christ is God and we have all we need in Him. We do not need to add traditions, philosophies, empty ideas, or anything else that would lead us away from being completely satisfied in Christ. Because in Jesus dwells all the fullness of God, and we are complete in Him.
Praise and glory and honor be to God our Father and our Lord Jesus Christ who gives us His Spirit! Amen.
