'Joy' in the Bible

You have cause for great joy in this, though it may have been necessary for you to be troubled for a little time, being tested in all sorts of ways,

To whom your love is given, though you have not seen him; and the faith which you have in him, though you do not see him now, gives you joy greater than words and full of glory:

But be glad that you are given a part in the pains of Christ; so that at the revelation of his glory you may have great joy.
