Bread has crust. It*s a scientific law of breadmaking.

It will have a crust, because it’s got an inside and an outside. And the outside will become crusted in the oven. BREAD CRUST holds a special meaning for Christians, or it should.
We pray, “Give us this day our daily bread,” and yet we look to tomorrow.  We ponder it, worry over it, plan it, hate it, anticipate it, can’t wait for it. We’re always wanting to live for tomorrow, live in tomorrow–almost like the proverbial green grass over the fence.
We want to make sure we’ll have tomorrow’s bread. So we worry over making right choices today, double-guessing our decisions today, regretting today and rejoicing in dreams of tomorrow. But all this time we forget that our daily bread has a crust.
Just like bread has a crust, days have an edge surrounding them front back and sideways.

We only have today.

Jesus said, “Sufficient for the day is the trouble thereof” just after he commanded his disciples, and those listening to [biblegateway passage=”Matthew 6:34″ display=”NOT WORRY ABOUT TOMORROW”]. All we have is today, and the grace we are given is sufficient for the day.  But as for tomorrow, that belongs to God.
Hebrews 4:16 says, “Let us then with confidence draw near to the throne of grace, that we may receive mercy and find grace to help in time of need.”  So, in our time of need (our right now) we can draw near and find grace.

Just like you cannot OBEY God for your friend,
or GIVE TITHES for your uncle from your salary,
or COMMIT your wife’s LIFE TO GOD for her,
you cannot BORROW strength or joy or success from tomorrow.
It doesn’t work like that.

But if we are like Martha, busy and concerned about many things, how can we not worry? It can help to remember the Bread Crust.

(If you’re limited in time, fast forward to 5:31)  “The sugars in the dough caramelize in the crust. They give us that beautiful brown crust. Only the crust can caramelize. It’s the only place that gets hot enough.”
So in essence, all bread by nature is going to have a CRUST. It is protecting the rest of the bread, it’s taking the heat and covering the dough. It is sacrificing itself, in a sense, in order to keep the inner bread soft and fluffy.

HOW TO FIGHT WORRY

Remember the crust to fight worry over tomorrow. The boundaries around your day protect you from the good, the bad, and the ugly of tomorrow. You have today. You are alive. Today. You have with you today things that make you happy.

Frame of Darkness

Yesterday, maybe you had someone or something you wish were still with you today. Tomorrow you maybe hope for someone or something to be with you. But today you have today. You have life, for sure. Today is framed by the darkness of yesterday’s night and the darkness of tomorrow’s morning. Darkness surrounds today. But you have today.
This framework is from God. The Bible starts by setting out limits. Light and darkness are limited, day and night, fish and birds. And time.

And God said, “Let there be lights in the expanse of the heavens to separate the day from the night. And let them be for signs and for seasons, and for days and years,  and let them be lights in the expanse of the heavens to give light upon the earth.” And it was so. [biblegateway passage=”Genesis 1″]

Stay within the Crust

That is, our days are limited. Our days have a crust about them. Delving into tomorrow promises nothing but dissatisfaction with today. It does no good. You don’t know what it holds, but God’s got it all under control. Stay within the crust.
Dwelling on yesterday’s failures promises nothing but discouragement with today’s efforts. It does no good. Forgive them. Forgive yourself. Stay within the crust.
Enjoy today to the limits, doing all you can “while it’s called today.”
“But exhort one another every day, as long as it is called ‘today,’ that none of you may be hardened by the deceitfulness of sin.” [biblegateway passage=”Hebrews 3:13″]

Time Limits and God

God defines himself as “[biblegateway passage=”Revelation 1:8″ display=”Who Was, and Is, and Is to Come”].” He encompasses all time dimensions, remains the same through each mode of time.
Human beings, however, are limited by today. We shed a million cells a day, so we are always changing. (Not to mention losing 60-100 hairs per day, though [biblegateway passage=”Luke 12:7″ display=”God knows how many we have”].) We are continually changing, growing, “metamorphasizing.” Tomorrow we are not the same person we were today. Our changeability is one reason Jesus told us to focus on today. We can’t change our height or add a [biblegateway passage=”Luke 12″ display=”single hour to our life”].

Lego-Bricks of Today

Next time you feel overwhelmed by the implications of today’s actions on tomorrow, remember that if you do today RIGHT, you don’t need to worry about tomorrow. Let me double the metaphor. Tomorrow is made up of the little Lego-bricks of TODAYs.

And if you have lived each one right, it makes a whole picture of right. And if you have lived each one

• reading your Bible
• praying
• sharing your faith
• repenting from sin
• praising God
• in acts of mercy and kindness,

then you’ve made a life of all the things you are [biblegateway passage=”Micah 6:8″ display=”meant to be doing”], as Jonathan Edwards said in 1723,

63. On the supposition, that there never was to be but one individual in the world, at any one time, who was properly a complete Christian, in all respects of a right stamp, having Christianity always shining in its true luster, and appearing excellent and lovely, from whatever part and under whatever character viewed: Resolved, to act just as I would do, if I strove with all my might to be that one, who should live in my time.
Resolutions of Jonathan Edwards

(He might have actually become that person he makes the supposition about.)
So let tomorrow remain in its darkness. And if tomorrow rises up against you like a Shrieking Eel, tell it to get back on the other side of the crust. All the promises of God are yours TODAY.
Work on the Brick that is today. Make TODAY the way you want your life to be. And do this one the best you can. To the edge of the crust. Then reap your reward, your daily REST. You will awake to another TODAY.
