I’m a (very) slow learner and have got to the end of another day wishing I’d learn the lesson in this quote from a sermon.
“The experience of not losing heart fades and must be renewed day by day. If you are a veteran Christian, you know this from experience. If you are newer in the faith, this is one of the most important things you need to know…
A New Dosage for Today’s Pain
Jesus said in Matthew 6:34, “Sufficient for the day is its own trouble.” Its own trouble. Its own wasting away. Its own destruction. Its own moths and rust and persecution and pain and dying. Each day has its own trouble. And the car of your hope and strength and joy is not meant to run on yesterday’s gas. The metabolism of your spiritual renewal is not meant to run on yesterday’s meal. The relief from your spiritual medicine does not come from yesterday’s dosage. The text says “day by day” the renewal comes! There are no spiritual booster shots that last for ten years. There are no meals designed by God to carry you for a year. There are no gas tanks in the car of your faith big enough never to need refueling. Look at what it says: “our inner self is being renewed day by day.”
Which is why the Bible not only said, “Sufficient for the day is its own trouble,” but also said, “The mercies of the Lord are new every morning” (Lamentations 3:22–23) — every day, day by day. There is new water flowing from the fountain. New food for today’s spiritual metabolism. New gas to drive today’s car. A new dosage to relieve today’s pain.
Why We Need Renewal Daily
…There is a reason God would design things this way. Don’t get in God’s face and complain to him that he is saving you this way. Don’t murmur against God that the path to heaven takes so many thousands of acts of renewal to keep from losing heart. Don’t tell God you know a better way. You don’t.
This is a conference under the banner, Soli Deo Gloria — to God alone be the glory. And what did verse 7 say: “We have this treasure in jars of clay [jars that need refilling, renewing day by day] to show that the surpassing power belongs to God and not to us.” God saves us through a thousand battles, a thousand renewals, so that we never, never forget that we are weak and he is our strength. He is our strength, our living water, our food, our gas, our medicine.
And the giver of the strength — the giver of hope and joy — gets the glory. That’s what the apostle Peter said: “Serve by the strength that God supplies — in order that in everything God may be glorified through Jesus Christ (1 Peter 4:11). The giver of the strength gets the glory for the service. That’s why we are weak and why we need renewals day by day so as not to lose heart.”
