(Mat 6:34 NIV)  Therefore do not worry about tomorrow, for
tomorrow will worry about itself. Each day has enough trouble of its
own.

You and I are to take our anxieties, and we are to come to Him and
say, "Manage these for me."

I heard a voice at evening softly say,
Bear not your yesterday
into tomorrow;
Nor load this week with last week’s load of
sorrow.
Lift all your burdens as they come
Try not to weight the
present with the by and by.
One step and then another,
take your
ways –
Live by the day!

                                                                      
– J. H. May

"Give your entire attention to what God is doing right now, and
don’t get worked up about what may or may not happen tomorrow. God will
help you deal with whatever hard things come up when the time
comes." (Matthew 6:34, The Message)

Today is the tomorrow you worried about yesterday.
