There are three parts to the plan. You are in the second or the middle part, the one in which you will be tested by temptation, by trials, perhaps by tragedy.
Remember this! The line, “And they all lived happily ever after” is never written into the second act of a play. That line belongs in the third act, when the mysteries are solved and everything is put right.
Until you have a broad perspective of the eternal nature of the plan, you won’t make much sense out of the inequities in life. Some are born with so little and others with so much. Some are born into poverty, with handicaps, and pain, with suffering. Some experience premature death, even innocent children. There are the brutal, unforgiving forces of nature and the brutality of man to man. We have seen a lot of that lately.
Do not suppose that God willfully causes that which, for his own purposes, he permits. When you know the plan and the purpose of it all, even these things will manifest a loving Father in Heaven.
(President Boyd K. Packer, Satellite Broadcast, May 7, 1995).
