One of the favorite arguments of Neo-Calvinists is to go to Col 1 to support every-square inch Christianity:
He is the image of the invisible God, the firstborn of all creation. For by him all things were created, in heaven and on earth, visible and invisible, whether thrones or dominions or rulers or authorities—all things were created through him and for him. And he is before all things, and in him all things hold together. And he is the head of the body, the church. He is the beginning, the firstborn from the dead, that in everything he might be preeminent. For in him all the fullness of God was pleased to dwell, and through him to reconcile to himself all things, whether on earth or in heaven, making peace by the blood of his cross. (Colossians 1:15-20 ESV)
But Rick Phillips puts limits on “all”:
What are some of the things that I have through the gospel of Jesus Christ? The answer is the cornucopia of salvation theology! I have justification so as to be accepted before God’s justice. I have adoption so as to be embraced into God’s fatherly love as a beloved child. I have sanctification as the Holy Spirit graciously works within me. And I have glorification, as the return of Christ is destined to admit him into his eternal presence. Through the gospel, I have the past, where Jesus lived and died on my behalf; I have the present, in which I am kept for eternal life by God’s grace; and I have the future, which holds no fear for those who are treasured in the hand of the Almighty. Through the gospel I have heaven, where my name is enrolled forever, and I have earth, over which my Savior exercises all power and authority. I have Christian fellowship through communion with the saints and I have participation in the church with its ordinances of nurture and care. Through the gospel I have perfect liberty to live above the world and sin and I have beloved bondage as a willing slave to Jesus Christ. Through the gospel, I have a new nature that partakes of the character of God, and I have the blessing of the law of God to guide me in the way of life. I have the Word of God shining within. I have prayer, which grants access to the very throne of grace. I have the sacraments, bearing the sign and seal of the covenant of grace. I have worship, service, sacrifice, and solace. Most of all, best of all, I have Jesus Christ – the whole Jesus Christ: Lord and Savior; Prophet, Priest, and King; Master, Helper, and Friend. And in union with Jesus Christ, together with communion in the gifts and graces of his blessed kingdom, through the gospel, I truly have all things!
That sounds like the Confession of Faith on Christian liberty:
The liberty which Christ hath purchased for believers under the gospel consists in their freedom from the guilt of sin, the condemning wrath of God, the curse of the moral law; and, in their being delivered from this present evil world, bondage to Satan, and dominion of sin; from the evil of afflictions, the sting of death, the victory of the grave, and everlasting damnation; as also, in their free access to God, and their yielding obedience unto him, not out of slavish fear, but a childlike love and willing mind. All which were common also to believers under the law. But, under the new testament, the liberty of Christians is further enlarged, in their freedom from the yoke of the ceremonial law, to which the Jewish church was subjected; and in greater boldness of access to the throne of grace, and in fuller communications of the free Spirit of God, than believers under the law did ordinarily partake of. (20.1)
In other words, that sounds like an otherworldly faith, not one that redeems cities, plumbing, and foreign policy.
I’m okay with that.
