The sermon opens the second of six debates recorded in the book of Malachi, turning to Malachi 1:6-14, where God brings a formal complaint against the priests and people of Israel over their corrupt worship. Having already proven, in the first debate, that he loves Israel despite the nation's suspicion that he does not, God now presses the reverse question: since I have loved you, why have you not returned that love in the offerings you bring me? The sermon's title names the argument that unfolds: God did not need to earn Israel's worship, yet in love he stoops to reason with his people rather than simply asserting his right to their best.

The text describes priests offering blind, lame, and sick animals as sacrifices, animals stolen or diseased, in direct violation of the law's requirement that sacrifices be without blemish. Israel's excuse, voiced in verse 13, is that worship has become "a weariness" — they regard giving anything to God as already generous, so any defect in the gift should not matter. The sermon reads this attitude as evidence of a deeper unbelief: Israel no longer believes God loves them, and so they see worship as a one-sided favor done for God rather than a response to a relationship. God counters with two comparisons that would have struck the original hearers forcefully. First, he compares himself to the Persian governor who rules over Judah: no one would dare present a blemished gift to a political ruler with power to tax and punish, so how much less should God, the true King, receive Israel's leftovers? Second, God compares himself to a father and a master, roles Israel already knows how to honor. A son honors a father who has loved and provided for him; a servant honors a master with a rightful claim over him. God is both to Israel — the one who redeemed them and to whom they belong — yet receives from them the honor a governor commands more readily than a father's love or a master's fear.

The sermon then turns to how this passage should be applied by Christians today, cautioning against a shallow reading where "giving God the best" is reduced to spending the most money — a bigger cross, a Steinway instead of a Yamaha, crisp new banknotes instead of worn ones. This impulse, the sermon says, gets something right, since a heart that wants to honor God will attend to such details, but it misses the actual diagnosis in the text: Israel's blemished offerings are a symptom, not the root problem. The root problem is that they do not love, thank, or delight in God, and so nothing about their worship, however costly, would satisfy what the text demands. Genuine best worship, the sermon insists, looks different depending on the worshiper's circumstances — the poor widow's two coins and Mary's undistracted attention at Jesus's feet are both counted as someone's best, because they flow from love rather than budget.

Moving from the Old Covenant to the New, the sermon explains that Old Testament animal sacrifice was never a transaction Israel performed to appease a needy God, as pagan religions imagined of their gods, but was itself God's gift — a gracious provision of forgiveness and a promised pathway back into relationship. The requirement for unblemished animals pointed forward to Jesus, the truly spotless sacrifice whose death alone accomplishes what animal blood never could. Because Christ has now offered the final, perfect sacrifice, the sermon turns to Romans 12:1 to show that sacrifice language still applies to Christians, but transformed: believers are called to offer their bodies as a "living sacrifice," meaning the whole of ordinary life — work, family, rest, finances — becomes worship, not merely the hour spent in a Sunday service. This living sacrifice remains blemished, since no Christian obeys perfectly, but it is nonetheless accepted, the sermon argues, because it is offered together with Christ's own perfect sacrifice; the blood of Christ covers what remains imperfect in the believer's obedience.

The sermon closes with two questions drawn from the text: whether the hearer has trusted in Christ's perfect sacrifice for sin, and whether believers are responding to God's grace by giving him their whole life as worship — in prayer, in resisting temptation, in serving family and others, and in gathered worship itself. Because Christ has already given his best for sinners, obedience need not feel burdensome; citing 1 John 5 and Hebrews 13, the sermon urges believers to offer a continual "sacrifice of praise," confident that what is blemished in them is received with joy through Jesus.
