King James Bible
"Giving thanks unto the Father, which hath made us meet to be partakers of the inheritance of the saints in light:"
Paul calls believers to express gratitude to God the Father, establishing thanksgiving as the proper response to divine grace. This phrase connects to the preceding verses about spiritual growth, showing that maturity includes recognizing God as the source of all spiritual blessings. The Father has qualified or made believers fit for something they could never achieve themselves. The passive voice emphasizes God's transformative work in making sinful humans worthy through Christ, not through personal merit or effort. Believers share in the promised inheritance belonging to God's holy people, described as existing 'in light'—a metaphor for God's realm of holiness, truth, and glory. This contrasts with the domain of darkness mentioned in the following verse, highlighting the transfer from one kingdom to another.
