James 2:12

For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all.

For he that said, Do not commit adultery, said also, Do not kill. Now if thou commit no adultery, yet if thou kill, thou art become a transgressor of the law.

For he shall have judgment without mercy, that hath shewed no mercy; and mercy rejoiceth against judgment.

What doth it profit, my brethren, though a man say he hath faith, and have not works? can faith save him?
