Forgiveness of sin is the heart of redemption in Christ. But that is different than saying God’s primary motivation for redemption is forgiveness of sin. In this sermon on “The Glory of God” from Ephesians 1:6, Dr. Martyn Lloyd-Jones remarks that errant thinking places the human being at the center of salvation rather than God. Instead, the glory of God is the great motive that led God to plan and purpose redemption in Christ. Christians are often lethargic about their salvation but Paul says Christians are redeemed to praise Him. Why should Advent illicit praise to God? Chiefly because in the coming of Christ the revelation of God’s glory is seen. Although the glory of God is difficult to define, the term implies God’s beauty, majesty, splendor, greatness, might and eternity. Dr. Lloyd-Jones walks through various passages in order to demonstrate how this theme runs throughout Scripture (Genesis 3:24; Exodus 40:34–37; Isaiah 6; Luke 2:14; 2 Corinthians 4:6). Placing the glory of God at the front of one’s mind can have great effects in evangelism. By emphasizing the glory of God in their proclamation of the gospel, Christians shall be much more apostolic in their method. While God is about His glory, the highest manifestation of that glory is found in the salvation of sinners.
