God has always called his people to be priests—offering sacrifices of thanks, praise, and devotion. In Christ, the ultimate sacrifice for sin has already been made, once for all, by our Great High Priest. Now, as God’s chosen people, we live as priests in a new way. Like the healed leper who returned to Jesus with praise (Luke 17:11–19), we bring our sacrifices: hearts broken by repentance, lips lifted in praise, prayers of faith, and gifts of our time, talents, and treasures. Worship trains us for this priestly life so that, here, there, and everywhere, we live as holy priests—offering our whole lives in gratitude to the God who has made us his own.
