Even though our outward man is perishing, yet the inward man is being renewed day by day. — 2 Corinthians 4:16

 The Concorde's exterior experiences extreme heat generation when in supersonic flight. Even when the outside air temperature is -56 C (-69 F), the temperature on the plane's exterior surface can reach 127 C (261 F). 

The plane is 9 inches longer at cruise speed than it is at rest due to the expansion generated by this heat. The aircraft's cabin floor is mounted on rollers so it won't expand, and four air conditioning units keep the space comfortable. The environment inside the plane doesn't change even while the outside is under extreme strain.

Paul highlighted how our "outward man" perishes under intense heat but our "inward man" is continually rejuvenated in the Scripture for today. Observe the contrast 

On the exterior, inside 

Every side was pressed. Not broken (v. 8) 

Perplexed Not dejected (v.8) 

Persecuted Not abandoned (verse 9) 

beaten down Not ruined (v. 9) 

Through Christ, we too can find inner strength when facing adversity (v. 11). Our responsibility is to use the Bible and prayer to renew our minds each day (Eph. 4:23) and to look beyond the fleeting to the everlasting (v. 18).

God's Word renews our thoughts, and God's Spirit gives us new energy. You cannot rely on your own strength;

There is a source of grace and strength in the heavens;

Visit that source to replenish your strength, and the life of Christ will be shown in you.
