'Rejoice' in the Bible

In this you greatly rejoice, even though now for a little while, if necessary, you have been distressed by various trials,

and though you have not seen Him, you love Him, and though you do not see Him now, but believe in Him, you greatly rejoice with joy inexpressible and full of glory,

but to the degree that you share the sufferings of Christ, keep on rejoicing, so that also at the revelation of His glory you may rejoice with exultation.
