You forget what Christ says of what even those who claim to be believers...
Matthew 7:22-23
22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
We tend to look on the outside and think men are just...
Matthew 23:28
Even so ye also outwardly appear righteous unto men, but within ye are full of hypocrisy and iniquity.
We saw that with what He told Samuel..
1 Samuel 16:7
But the Lord said unto Samuel, Look not on his countenance, or on the height of his stature; because I have refused him: for the Lord seeth not as man seeth; for man looketh on the outward appearance, but the Lord looketh on the heart.
