In this sermon by Tim Keller, he delves into the Book of Isaiah, focusing on chapter 58, verses 1 through 14. The scripture calls for a bold proclamation of the people's sins and rebellion against God. It criticizes superficial fasting and religious observances that lack true compassion and justice for the oppressed. God defines true fasting as actions that break the chains of injustice, free the oppressed, feed the hungry, provide shelter for the homeless, clothe the naked, and support one's kin.
Keller emphasizes the sermon's focus on social justice, highlighting the paramount importance of justice in God's eyes. He connects this message to the essence of the gospel, illustrating how Jesus embodies and fulfills divine justice. The sermon also ties into the church's mission, specifically regarding the Easter sacrificial offering aimed at supporting justice initiatives and the church's plans to plant new congregations in the city. These new churches are encouraged to engage deeply in acts of justice and mercy, reflecting the sermon's core message.
The passage from Isaiah 58 is dissected into three main teachings about justice. First, it confronts the audience with the critical importance of justice, pointing out that religious practices without a relationship with the oppressed are meaningless to God. Second, it outlines a comprehensive view of justice that transcends mere ritual, demanding active involvement in the lives of the marginalized. Lastly, Keller discusses the transformation required to engage in true justice, involving a heart that seeks mercy and champions the cause of the vulnerable.
Keller explores the biblical concept of justice, starting with an Old Testament story where the expectation of divine action is flipped, showcasing God's alignment with the poor and marginalized rather than the powerful. This theme continues into the New Testament, where Jesus criticizes the religious elite for neglecting the essentials of justice and identifies with the least in society. Keller underscores that a relationship with God is inherently linked to how one treats the needy.
The sermon further examines various theories of justice, comparing them to the Bible's holistic approach, which includes equal treatment, special concern for the vulnerable, and the call for generosity beyond equality. This biblical justice is portrayed as requiring both advocacy for the oppressed and radical generosity.
Addressing the American context, Keller challenges the common but unbiblical notion that helping the poor is optional. He draws from the book of Job to argue that failing to share wealth with the needy is unjust, as all blessings are ultimately from God. This perspective is expanded to critique societal structures that perpetuate inequality, highlighting the moral imperative to act against such injustices.
Keller confronts the inadequacy of guilt as a motivator for justice, critiquing both religious and secular approaches that fail to inspire lasting change. Instead, he proposes a motivation rooted in the beauty of justice, suggesting that true commitment to justice arises from a joy in doing what is right, inspired by the gospel's message of grace and Jesus' sacrifice.
Reflecting on the gospel's power to humble and transform, Keller shares personal insights into overcoming superiority and emptiness through the love and justice exemplified by Jesus. This understanding of grace and the beauty of Jesus' life, death, and resurrection motivates believers to pursue justice not out of duty, but as a response to the greatest beauty they have encountered.
The sermon concludes with a prayer for the ability to see and pursue justice through the lens of the gospel, recognizing Jesus' identification with the poor and oppressed as the ultimate expression of God's love and a model for Christian living.
