There is a time for everything,
and a season for every activity under heaven:

a time to be born and a time to die,
a time to plant and a time to uproot,
a time to kill and a time to heal,
a time to tear down and a time to build,
a time to weep and a time to laugh,
a time to mourn and a time to dance,
a time to scatter stones and a time to gather them,
a time to embrace and a time to refrain,
a time to search and a time to give up,
a time to keep and a time to throw away,
a time to tear and a time to mend,
a time to be silent and a time to speak,
a time to love and a time to hate,
a time for war and a time for peace.

… He has made everything beautiful in its time. He has also set eternity in the hearts of men; yet they cannot fathom what God has done from beginning to end.
-Ecclesiastes 3:1-9, 11

Yes.
There is a time for everything.
A time for every joy and every sorrow.
God knows our hearts, our desires, needs and fears. He also know all of history, all of the future, and all of eternity.
Being human, we are finite. God alone has infinite knowledge and understanding. We cannot know what is to come, and we only have a partial knowledge of the present.
That does not stop us from planning our futures, though. We need to be reminded (over and over, it seems) that the times we desire may not be the times God has in mind.
We may not see the why behind a perceived “delay” or sorrow, but we can rest in knowing these things: God is sovereign, God is faithful, and God is love.

“As the heavens are higher than the earth,
so are my ways higher than your ways
and my thoughts than your thoughts.”
-Isaiah 55:9

Oh, yes! He is the Eternal One, the Ancient of Days. He sees the end from the beginning. I can rest in that.
