In 1992, Tim Keller pointed to a startling statistic from the New York Times: in 1960, one out of every 20 births was to a mother without a father living at home; by 1992, it was one out of four. He called this a "cultural earthquake." But Keller’s point was not to lament human fathers. Instead, he used Father’s Day to argue that the deepest human need is not for a better earthly father, but for the perfect, undying fatherhood of God—a relationship that, according to Christianity, is only possible through the legal and costly act of adoption in Christ.

The Radical Claim: Creator Becomes Father

Keller begins by drawing a sharp distinction. Just because God is your creator does not mean he is your father. He uses the analogy of Henry Ford: Ford was the "father of the Model T," but he did not have the cars around his dinner table or tuck them into bed. Every other religion, Keller argues, offers a relationship with the creator as a servant, student, or follower. Christianity alone claims that through Christ, the creator can become your father. This is not a natural state. Keller insists that the Bible does not teach that everyone is automatically a child of God. Adoption requires a deliberate, legal action on the part of the Father.

What you'll learn

1 (00:03) **Introduction: The Radical Claim of Christianity** - The sermon opens with the central thesis: that through Christ, your Creator can become your Father, a claim unique to Christianity.
2 (02:10) **The Problem of Imperfect Human Fathers** - Keller uses Father's Day to acknowledge the rarity and imperfection of human fatherhood, setting up the need for a perfect divine Father.
3 (05:30) **The Prodigal Son: Adoption at the Elder Brother's Expense** - Keller uses the parable of the prodigal son to explain the mechanism of adoption: it is a legal action made possible only by the sacrifice of Jesus, the true Elder Brother.
4 (11:02) **The Roman Legal Framework of Adoption** - Keller explains the Greco-Roman concept of "huiothesia" (adoption) to show it is a change of legal status, not nature, and the highest possible status.
5 (14:17) **Adoption is Higher Than Justification** - Keller argues that adoption is a greater blessing than forgiveness or justification, using the analogy of a governor's actions toward a criminal.
6 (15:09) **Our Sonship: Like Christ, Yet Unlike Christ** - Keller explains the paradox of our adoption: we are loved as much as Jesus, but we do not merge into the Godhead.
7 (22:51) **The Subversive Nature of "Sonship"** - Keller addresses the use of the masculine term "sons" for all believers, explaining its radical, subversive meaning in the Roman world.

Show Notes

God moved heaven and earth to be our Father. Rather than just forgiving our sins through Jesus Christ, he invites us to sit at the family table with him as his very own sons and daughters.

All too often, we live and act as slaves instead of cherished children, blown about by the emotional highs and lows of our circumstances and defensive about our standing in life. But the truth is that our adoption grants us a wonderful security in Jesus that we can call upon daily.

Let’s look at 1) how God’s adoption of us is far more radical than it seems, and 2) how we can rest secure as sons instead of slaves.

This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on June 14, 1992. Series: Salvation From the Outside In. Scripture: Ephesians 1:4-8.
