1 Peter 1:17

And if ye call on the Father
Of Christ, and of all the saints; or "seeing" ye do. This is a fresh argument, engaging to holiness of life and conversation. Invocation of God includes the whole worship of him, the performance of every outward duty, and the exercise of every inward grace, particularly it designs prayer; and whoever are concerned in one, or the other, God will be sanctified by all them that draw nigh unto him: or the phrase may here intend an asserting God to be their Father, under the influence of the spirit of adoption; and all such that do claim so near a relation to God ought to honour and obey him, and to be followers of him: whoever call God their Father, and themselves his children, ought to be careful that they do not blaspheme, or cause to be blasphemed, that worthy name by which they are called:

who without respect of persons judgeth according to every man's
work.
This is another reason why men should be holy, taken from the general judgment; for this God that is a Father, is also a judge. There is a judgment after death, which is sure and certain, and reaches to all persons and things; and though the Father judges no man, but has committed all judgment to the Son, yet he will judge everyone by that man Christ, whom he has ordained to be the Judge of quick and dead: before his judgment seat all must stand, where they will be impartially, and without respect of persons, tried; no account will be had of what nation and place they are, whether Jews or Gentiles, or of this, or the other country, unless to aggravate or lessen their condemnation; for it will be more tolerable for Tyre and Sidon, for Sodom and Gomorrah, than for such who have been favoured with a Gospel revelation, and believe it not; nor from what parents they have descended, for the soul that sins, that shall die; nor of what age and sex they are, small and great shall stand before him; nor of what state and condition, rich or poor, high or low, bond or free; or of what religious sect and denomination, or whether they have conformed to some external things or not; no regard will be had to any outward appearance or profession. The Judge will not judge according to the sight of the eyes, and outward view of things; for he looks on the heart, and knows the secret springs of all actions; and according thereunto will he judge and pass the sentence; and therefore what manner of persons ought men to be, in all holy conversation and godliness? Hence it follows,

pass the time of your sojourning here in fear;
the people of God in this world are "sojourners", as all their fathers were; they are not natives of the place in, which they are; though they are in the world, they are not of it; they were natives of it by their first birth, but by their second they are born again from above, and so, belong to another place; they are of another country, even an heavenly one; are citizens of another city, a city which, has foundations, whose builder and maker is God, their citizenship is in heaven; and there is their Father's house, which is not made with hands, and is eternal; and there lies their estate, their inheritance; and though they dwell here below, neither their settlement nor their satisfaction are here; they reckon themselves not at home while they are on earth, and are strangers in it, to the men of the world, and they to them; with whom they have not, or at least ought not to have, any fellowship. It is indeed but for a "time", that they are sojourners, not an eternity; which time is fixed, and is very short, and will be quickly gone; it is but a little while, and Christ wilt come and take them home to his Father's house, where they shall be for ever with him; for it is only here on earth that they are pilgrims and strangers: and while they are so they should spend their time "in fear"; not of men nor of devils, nor of death and judgment, hell and eternal damnation; for such a fear is not consistent with the love of God shed abroad in the heart, and is the effect of the law, and not encouraged by the Gospel; is in natural men, yea, in devils themselves; but in the fear of God, and which springs from the grace of God, and is increased by it; is consistent with the strongest acts of faith, and with the greatest expressions of spiritual joy; is opposite to pride and self-confidence, and includes the whole worship of God, external and internal, and a religious conversation, in humility and lowliness of mind.
