A Bible web-reference says that the word “rejoice” occurs 192 times in the Scripture, and virtually every one of them is in the imperative form: thou shalt rejoice!
And ye shall rejoice before the LORD your God, ye, and your sons, and your daughters, and your menservants, and your maidservants, and the Levite that [is] within your gates . . . Deuteronomy 12:12
Look at these words: But let the righteous be glad; let them rejoice before God: yea, let them exceedingly rejoice. (Psalm 68:3)
Other reference reveal REJOICING as a personal decision, a response to God’s imperative:
Because thou hast been my help, therefore in the shadow of thy wings will I rejoice. (Psalm 63:7)
Clearly, God has chosen a rejoicing life for His own, and here in Cor Unum we choose a rejoicing life in response. How shall we not? The worst thing that could ever happen to us, never will . . . eternal separation from God was our doom, but Jesus Christ has bridged the gap and brought us near. The best thing that could ever happen to us is ours already . . . we are born again of a new Spirit, and He has come to abide with us forever . . .
. . . and we will REJOICE together at the Wedding Supper of the Lamb!
