Hebrews 11:6

And without faith it is impossible to be well-pleasing unto him; for he that cometh to God must believe that he is, and that he is a rewarder of them that seek after him.

Westcott noted that the faith described here has two elements: (1) the belief that God is, and (2) that he is morally active; in other words, it is a faith in the existence of God and in the moral government of God.[13] Furthermore, the expression "seek after him" as in the English Revised Version (1885), falls short of the power of the KJV rendition which reads, "diligently seek him." Although the word "diligently is not in the text, the meaning assuredly is; for, as Westcott wrote, "Wherever it occurs in the New Testament in the sense of `searching' (the word for SEEK) suggests the notion of strenuous endeavor."[14] In the light of this, a preference for the KJV rendition of this verse is not amiss.
