NIV....Eph 3.9 and to make plain to everyone the administration of this mystery, which for ages past was kept hidden in God, who created all things.
The NIV takes away the job details( The revelation of the Mystery) for The Church the Body of Christ! Thus causing Blindness to the Gospel of Christ, the power of God unto salvation!
KJB....Eph 3:9 And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:
NO ONE WILL EVER SEE WHAT THE FELLOWSHIP OF THE MYSTERY IS USING AN NIV. IT IS NOT A BIBLE!
