12 giving thanks to the Father, who has qualified you to share in the inheritance of the saints in light.
The third refrain describing the worthy Christian life beckons the believer to gratitude. Indeed, one of the greatest hallmarks of the Christian faith is that of a cultivated gratitude for the presence and work of God. So it is with genuine believers that gratitude overflows from the soul into the world around them. In Ephesians 5:4, gratitude is urged as a defining character trait of the Christian’s speech. In Philippians 4:6, Christians are urged to combat anxiousness with gratitude. In 1 Thessalonians 5:18, Paul calls believers to “give thanks in all circumstances.” In 2 Thessalonians, the saints are encouraged to give thanks for salvation. In 1 Timothy 2:1-2, Paul calls for prayers of thanksgiving to be made for everyone, including pagan Kings. In 1 Timothy 4:1-5, Christians are urged to give thanks for everything they receive.
The spirit of gratitude, cultivated in the life of a believer is absurd. It is a spirit that thanks God for persecution, famine, destruction, as well as freedom, plenty, and life. This Spirit urged among the believers of the first century, no doubt, seemed even more obscene. As Paul urges Christians to express gratitude to God, the Christian religion is experiencing tremendous persecution. Yet, in the face of rejection and death, Christians are to say thanks. Thanks for destruction? Christians are to be grateful for the loss of everything? Truly? Yet, it is the Spirit of God that lives within believers and empowers such obscene gratitude. Though the world collapse and reject everything the Christian holds dear, still, the Christian contradicts such resounding rejection with love and gratitude. The Christian life is a contradiction of worldly values. Believers seek a value that stands in stark contrast with the values of this world and its systems. It is precisely this contradiction that is manifest in the Christian’s gratitude.
Where does such profound contradiction come from? A Christian’s faith results in gratitude for all things because a Christian’s faith is from the God who is over all things. It is “the Father” from whom the ability to respond in gratitude is received. It is also to Him that gratitude is given. He has granted life where there was death and brought light into darkness (c.f. Ephesians 2:1-8). The God of all things, the Maker and Sustainer of all life, has granted Christians an inheritance where there once was none.
Note: He “qualified” believers for this inheritance. The word used here means “to make sufficient” or “to render worthy.” Consider that for a moment. God has made Christians worthy. He has, in His infinite grace, established those who believe in Him as worthy. Those who love Christ need not strive to be worthy. They simply are worthy. They are worthy because the Father has made them worthy. He has changed their condition from sinful, unworthy, and wicked to saintly, worthy, and righteous.
All mankind rejects God. There is no one who is righteous on their own, indeed, all are sons of disobedience (c.f. Romans 1-3 and Ephesians 2). Yet, God, in His kindness, saved those who believe in Him, granting orphans adoption. Forgiving those who deserve death. From this realization, springs gratitude. Mankind is wicked and deserving of death, yet God’s love and favor persist. No person can look upon the face of God, behold His majesty and glory and persist in self-righteous pride. No person can be confronted with the reality of His holiness and still deny His goodness and grace. In the face of such a God, the only acceptable response is gratitude.
Ponder for a moment the truth that He has changed the soul of those who believe. The very nature of the individual who confesses Christ has been displaced and replaced with a new nature that is entirely changed. A nature that has been made worthy of the holiness of God. A nature that has been qualified! Thus, the worthy Christian life is one in which this deep and powerful truth transcends our mundane existence and draws us to our knees in gratitude. This gratitude is present in the light!
The light… everyone can see the Christian. The flaws and weaknesses. The failures and trivial affections. Christians receive an inheritance as children of “light.” There is no hiding in the light. One is entirely exposed in the light. Even so, the stark contrast of the unworthy sinner who has been deemed worthy by God and the holiness of God must draw the Christian to gratitude. For such a change of condition is too great to be observed passively. It demands an exchange of self-righteousness for humble gratitude. Christians cannot stand in pride or pretense. They have been exposed before a holy and righteous King who has deemed them worthy by His own act of benevolence.
