Read John 16:16-28

[Jesus said] “Amen, Amen, I tell you: You will weep and wail, but the world will rejoice. You will become sorrowful, but your sorrow will turn to joy.” - John 16:20 (NLT)

God’s ways are not our ways. When He acts, and we look on only with human eyes, we may be sad or disappointed. But God’s purposes will come to completion, and then we will have joy. This has been true since the crucifixion (sadness) and resurrection (joy), and is still true today.
