A pair of grand old hymns, "Trust and Obey" and "More Love to Thee", embody the essence of Deuteronomy. Above all, this book stresses the importance of obedience to what God has commanded. In what area of my life is it most difficult for me to obey God? What is God asking me to do today?
However, Deuteronomy also makes it clear that God is not interested in mere rote obedience. He desires obedience that springs from a heart of love. Jesus quoted Deuteronomy 6:4-5 when asked to name the greatest commandment of all (Matthew 22:37; Mark 12:30; Luke 10:27). Do I love God with all my heart, soul, mind and strength?
Deuteronomy also emphasizes the parents' role in teaching their children to love God and walk with him (for example, see 6:4-9). If God has blessed you with children (or grandchildren!), what might be a creative way you can capture their imaginations with God's Word?
