He has made everything beautiful in its time. Also, he has put eternity into man's heart, yet so that he cannot find out what God has done from the beginning to the end.
In the day of prosperity be joyful, and in the day of adversity consider: God has made the one as well as the other, so that man may not find out anything that will be after him.
Not only that, but we rejoice in our sufferings, knowing that suffering produces endurance, and endurance produces character, and character produces hope.
