It takes humility to make great art, to recognize that there is something (and Someone) outside ourselves that is far greater than we will ever hope to be. All the more so for the Christian, who knows and believes that God is the best and most creative Artist of us all. C.S. Lewis understood this, and it's why he made this statement in a 1975 journal article:
The greatest poems have been made by men who valued something else much more than poetry.
--C.S. Lewis
