Ephesians 4:12
KJV
For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ:
NIV
to equip his people for works of service, so that the body of Christ may be built up
The KJV structures three distinct yet parallel purposes separated by commas, while modern versions combine the first two into one. In the KJV, “perfecting” signifies the saints’ spiritual growth and sanctification unto completeness, whereas modern versions’ “equipping” makes it seem like the saints are merely given the tools to do good works, without any emphasis on sanctification or completeness.
