When the Hebrews rebuilt the temple in the days of Ezra, it is written they celebrated the dedication of this house of God with joy. Ezra 6:16
When the Hebrews rebuilt the walls of Jerusalem in the days of Nehemiah, it is written they did celebrate the dedication with gladness, both with thanksgivings and singing, with cymbals and stringed instruments and harps. Neh 12:27
The Bible speaks of celebrating Passover, the New Moon feasts, Feast of Tabernacle, and much more.
You also celebrate birthdays, marriages, graduations, and much more.
God wants you to celebrate but to celebrate with Him, in Him, through Him, and to Him.
God’s celebration is eternal and joyful!
Celebrating in God is holy, pure, and righteous.
As the Message Bible puts it, Celebrate God all day, every day. I mean, revel in him! Phil 4:4
