This sermon introduces a series on the book of Deuteronomy, Moses’ final sermons to Israel, delivering God’s instructions for a new generation on the cusp of entering the promised land. It reminds us that Deuteronomy is God’s authoritative, inspired word, not merely a legal code but pastoral teaching aimed at guiding God’s covenant people. The sermon provides seven reasons for studying Deuteronomy: it is God’s word, challenges misconceptions about the law, is commended by Jesus, teaches about covenants, fosters Christian maturity, offers wisdom for society, and aims for conviction and godliness. Drawing parallels for Christians today, it highlights how, like Israel, believers are redeemed by grace and called to faithful obedience to advance Christ’s kingdom, trusting in God’s promises and presence.
