While many congregations conclude the worship service with a closing hymn or song, the true end of the service is the Benediction. This makes perfect sense. We begin the service in the name of God as we speak the Invocation. And we end the service in the name of God as He blesses us in the Benediction.
The words of the Benediction are drawn from the Scriptures, particularly from Numbers 6:24-26. But look at the verses before and after the blessing.
The LORD spoke to Moses, saying, “Speak to Aaron and his sons, saying, Thus you shall bless the people of Israel: you shall say to them,
The LORD bless you and keep you; the LORD make his face to shine upon you and be gracious to you; the LORD lift up his countenance upon you and give you peace.
“So shall they put my name upon the people of Israel, and I will bless them.”
This is how the priests (which Aaron is in charge of) are to bless and put God's name upon God's people. Notice LORD is in all caps here. This is God's divine name, Yahweh, being placed on the people.
Our lives as Christians begin in God's name in Baptism. Our worship services begin in God's name in the Invocation. Our worship services end with God's name being placed upon us in this Benediction. And our lives as Christians end in God's name too. This is one of the prayers I will pray at a burial or a funeral.
May God the Father who created this body; may God the + Son, who by His blood redeemed this body; may God the Holy Spirit, who by Holy Baptism sanctified this body to be His temple, keep these remains to the day of the resurrection of all flesh.
The name of our God begins, blesses, ends, and brings us through all of life. From baptism to burial and beyond, God's name reigns over us.
In the name of the Father and of the + Son and of the Holy Spirit.
