C.S. Lewis' First and Second Things

If you put what is second before what is first, you lose both first and second. Second things do not have the strength to hold up things in life as first things do. Second things are temporal; they are what we can see. First things are what is unseen and what holds everything together. Seek first the kingdom of God and his righteousness, and all these things will be added to you. -Matthew 6:33
