Moses instructs the people how to worship the Lord. In contrast to the practices of the people who live in Canaan, Israel will worship in one central location. They will all come together along with their families and offerings and sacrifices. They will enjoy a meal and verse 7 concludes by saying “…and you shall rejoice, you and your households, in all that you undertake, in which the Lord your God has blessed you.”
The worship ceremony for the people of God shall be joyous! It was to be a celebration of God’s many blessings and a time of family and friends and unity in a corporate setting at the place God chose to establish His presence.

As believers our celebrations are always to be joyous because Christ made the sacrifice for us. It’s interesting to notice that the two shortest verses in the New Testament are intimately related. Some argue about which the shortest is.  They are “Jesus wept” and then 1 Thessalonians 5:16, “rejoice evermore.” There’s a beautiful connection between these two; because Jesus suffered (wept), we rejoice!

Just as Moses told the people “You shall rejoice…” So too does Paul tell us “rejoice evermore.”
