Grace as it's needed

I've been reading Transforming Grace by Jerry Bridges. It's about God's grace, not only to save, but to sanctify us throughout our lives, in good times and in hard times. I like the way he words our daily dependence on the Lord, and the need to be content in the circumstances that He has placed us in- 

God always gives us what we need, perhaps sometimes more, but never less. The spiritual equivalent to food and clothing (1 Timothy 6:8) is simply the strength to endure in a way that honors God. Receiving that strength, we are to be content. We would like the "luxury" of having our particular thorn removed (2 Corinthians 12:8-10), but God often says, "Be content with the strength to endure that thorn." We can be confident that he always gives that. 

Be content with the strength to endure. wow. Mr. Bridges makes an illustration of God's distribution of grace by going to Exodus 16:16-21 and noting how God provided food for the Israelites in the wilderness. Every day the people were to gather as much as they needed for that day, and not to save a supply for later. I need to look to Him for strength daily - physical, emotional, and spiritual. I can't store up grace for next month or next year. He provides day by day, and sometimes even hour by hour. But His grace is sufficient, and I have the opportunity to give Him praise by simply resting in it. :)
