“Adoption in Christ” by Marcus Peter Johnson

“Jesus Christ is an inexhaustible fountain of blessing to us (Eph. 1:3; 1 Cor. 1:30). When He gives Himself to us that we might enjoy Him, He is not only our justification—the One through whom we experience the forgiveness of sins and the fellowship of His righteousness—He is also our sanctification— the One through whom we are made holy and are transformed into His image.

Yet He is the source of yet another blessing, one so amazing that it would be blasphemous to suggest if it were not true. In our union with Christ, the only begotten Son of God, we participate in what is most precious to Him: His relationship with His Father.

We are, in union with Christ, adopted into the family of God; we become the children, the sons and daughters, of the Most High God. The blessing of adoptive sonship answers another desperate need we have as sinners.

Whereas justification (a forensic benefit) addresses the guilt and condemnation that accompanies sin, and sanctification (a transformative benefit) addresses the depravity and pollution of our nature, adoptive sonship (a familial benefit) addresses our estrangement and alienation from God…

The neglect of adoption in the soteriological understanding of the church is sorely lamentable, for our participation in the sonship of Jesus Christ is indeed basic to the New Testament gospel.

From the biblical teaching on adoption, we learn that we are restored to a familial intimacy with God the Father, through which we are assured of His eternal fatherly care and provision, a love and indulgence that exceeds our imaginations.

We learn that our relationship to God is so radically changed that we go from being ‘children of wrath’ (Eph. 2:3) to His beloved sons and daughters, a relationship in which the Father vouchsafes to care for our every need.

Perhaps even more amazing, we learn that by sharing in the Son we share in His rights as the Firstborn and only begotten Son of God—we are ‘heirs of God and fellow heirs with Christ’ (Rom. 8:17).

Our minds and hearts should surely stagger under the weight of this reality. It simply exceeds our comprehension.

All of this makes defining adoption concisely a rather difficult task. Nevertheless, here is my effort:

Adoption is that benefit of being united to the Son of God through which we share in His sonship with the Father, become the beloved children of God, and enjoy all the privileges and rights of being included in God’s family.

“His grip on us is unbreakable” by Marcus Peter Johnson

“The gospel is full of inconceivably extravagant promises from our Father. He has given these promises to provide His children with the full assurance of His freely given, irrevocable love, and they are grounded in His steadfast, immovable, unchangeable faithfulness.

What God promises He will infallibly bring to pass. And all the promises the Father makes are bound up inextricably in Jesus Christ, in whom they are fulfilled and completed: ‘For no matter how many promises God has made, they are ‘Yes’ in Christ’ (2 Cor. 1:20, niv1984).

In order to bring to fruition all that He has promised us, God joins us indissolubly to the One in whom all the promises are contained, fulfilled, and secured. It is only in Christ that we benefit from any of God’s lavish pledges.

Thus, the assurance believers have that God will infallibly save them, and that they will never cease to be saved, is rooted in their being joined to the Savior. The Father gives us to the Son, and it is the Father’s will that the Son save us to the uttermost:

‘And this is the will of Him who sent me, that I should lose nothing of all that He has given me, but raise it up on the last day. For this is the will of my Father, that everyone who looks on the Son and believes in Him should have eternal life, and I will raise him up on the last day’ ( John 6:39–40).

Our separation from Jesus Christ would mean nothing less than the failure of the Son to accomplish the Father’s will. Once joined to Christ, believers will never be separated from Him.

This is not because our grasp on Christ is so strong, but because His grip on us is unbreakable. We are not only perfectly and eternally preserved in Christ because His grasp is insuperable, but, should we need even greater assurance, Jesus tells us that His hold on us is undergirded by the invincible grasp of His Father:

‘I give [my sheep] eternal life, and they will never perish, and no one will snatch them out of my hand. My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father’s hand. I and the Father are one’ ( John 10:28–30).

The Son and the Father have a common and mutually re-enforcing grasp on those who belong to them. Indeed, we can say more: our preservation in Christ is anchored in the personal relations and purposes of the Father, Son, and Spirit.

The Father gives us to His Son through His Spirit or, alternatively, the Spirit joins us to the Son, and through the Son to the Father (John 14:16–20). Only a breach in the common unity and will of the triune Godhead could sever us from Jesus Christ.”
