A holy man!

(J.C. Ryle)

Holiness is the habit of being of one mind with God, according as we find His mind described in Scripture. It is the habit of . . .
  agreeing with God's judgment,
  hating what He hates,
  loving what He loves, and
  measuring everything in this world by the standard of His Word.

A holy man will strive to be like our Lord Jesus Christ. He will not only live a life of faith in Him and draw from Him all his daily peace and strength, but he will also labor to have the mind that was in Him and to be conformed to His image!
