If you call on him as Father, who without respect of persons judges according to each man's work, pass the time of your living as strangers here in reverent fear:
Judgeth according to every man’s work - He judges each one according to his character; or to what he has done, Revelation 22:12. See the notes at 2 Corinthians 5:10. The meaning is: “You worship a God who will judge every person according to his real character, and you should therefore lead such lives as he can approve.”
