-15 asks the question: What does God want of us? God wants our joyful thanks for his grace, and he also wants our wholehearted obedience. But we can't do this... So what do we do as God's people when we fail and our delight in worship becomes duty? Well, we look to the one who could say with wholehearted conviction the words of Deuteronomy 26. We look to Jesus, the author and perfecter of our faith, and we delight, we rejoice in our worship for the glory of God the Father, through God the Son, by the power of God the Holy Spirit. Mark Roberts helps us think deeper through these passages in Deuteronomy.
