For he flattereth himself in his own eyes, until his iniquity be found to be hateful.

For if a man think himself to be something, when he is nothing, he deceiveth himself.

But Jesus did not commit himself unto them, because he knew all men, And needed not that any should testify of man: for he knew what was in man.

Most men will proclaim every one his own goodness: but a faithful man who can find?

And I will kill her children with death; and all the churches shall know that I am he which searcheth the reins and hearts: and I will give unto every one of you according to your works.
