Heck yes! Christians should celebrate the greatest events in history and one yet to come.
The greatest events in history include:
a. Creation: God the Son creates all things, the universe, angels, man in God's image.
b. Incarnation: God the Son is conceived and born of the virgin Mary.
c. Ministry: God the Son lives a Holy and sinless life and ministers the word of God and healing to those in need.
d. Atonement: God the Son is crucified for the sin of the world and the salvation of men
e. Resurrection: God the Son rises from the grave for our justification.
f. Ascension: God the Son ascends to the Father and is enthroned in heaven.
g. Birth of the Church: God the Son baptises believers with the Holy Ghost and fire.
h. Parousia: God the Son returns to judge the world and reward His saints.
These are the greatest events, all worth celebrating daily, the last one in advance.
