This message tackles the question of morality by asking what standard determines good and evil. Drawing on the Euthyphro Dilemma, it argues that if morality is not grounded in God it dissolves into chaos, but if it is merely commanded by God apart from His nature it becomes arbitrary. The message points instead to the Triune God as the eternal, personal ground of all morality, so that God’s own character – not human opinion – defines what is good.
The sermon argues that people cannot escape moral absolutes even while denying God, because every moral judgment secretly borrows a fixed standard that only a real God can supply (“the impossibility of the contrary”). It ties God’s holy law to Christ, who is presented as the power and wisdom of God who answers the law’s demand for justice on behalf of sinners.
