Self-esteem?

Spurgeon, "THE FIRST LAST, AND THE LAST FIRST"

The man who thinks that he is holy has never seen the holy God.

If he had -- if he had ever beheld him, he would say with Job,
"I have heard of you by the hearing of the ear, but now my eye
sees you. Wherefore I abhor myself, and repent in dust and ashes."

The superlative perfection of the Lord God, and the
absolutely perfect example of our Lord Jesus Christ,
are such that if a man has ever had communion with
these, he shrinks into nothing in his own esteem.

Paul, though he is not a whit behind any of the apostles,
yet calls himself less than the least of all saints, and
describes himself as having been the chief of sinners.

Ah, beloved! a LOW IDEA OF SELF is one of the
labels with which God marks the best of his
possessions; therefore, do not be proud.
