1 Peter 1:17

And if ye call on the Father - That is, if you are true Christians, or truly pious - piety being represented in the Scriptures as calling on God, or as the worship of God. Compare Acts 9:11; Genesis 4:26; 1 Kings 18:24; Psalms 116:17; 2 Kings 5:11; 1 Chronicles 16:8; Joel 2:32; Romans 10:13; Zep 3:9; 1 Corinthians 1:2; Acts 2:21. The word “Father” here is used evidently not to denote the Father in contradistinction to the Son, but as referring to God as the Father of the universe. See 1 Peter 1:14 - “As obedient children.” God is often spoken of as the Father of the intelligent beings whom he has made. Christians worship Him as a Father - as one having all the feelings of a kind and tender parent toward them. Compare Psalms 103:13, following.

Who without respect of persons - Impartiality. One who is not influenced in His treatment of people by a regard to rank, wealth, beauty, or any external distinction. See the Acts 10:34 note, and Romans 2:11 note.

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.”

Pass the time of your sojourning - “Of your temporary residence on earth. This is not your permanent home, but you are strangers and sojourners.” See the notes at Hebrews 11:13.

In fear - See the Philippians 2:12 note; Hebrews 12:28 note. With true reverence or veneration for God and His law. Religion is often represented as the reverent fear of God, Deuteronomy 6:2, Deuteronomy 6:13, Deuteronomy 6:24; Proverbs 1:7; Proverbs 3:13; Proverbs 14:26, et saepe al.
