In 2 Cor 3:6 Paul draws a strong contrast between letter and spirit/breath:

> 
> NIV 2 Cor 3:6 He has made us competent as ministers of a new
>  covenant—not of the letter but of the Spirit (breath); for **the
>  letter kills, but the Spirit (breath) gives life.**
> 
> 
> 

Whereas in 2 Tim 3:16 he sees them as being complementary:

> 
> New International Version 2 Tim 3:16
>  **All Scripture (writings) is God-breathed and is useful** for teaching, rebuking, correcting and training in righteousness,
> 
> 
> 

Does this constitute a contradiction or are they actually complementary?
