I Peter 1:18

Another motive to reverential, vigilant fear (Pe1 1:17) of displeasing God, the consideration of the costly price of our redemption from sin. Observe, it is we who are bought by the blood of Christ, not heaven. The blood of Christ is not in Scripture said to buy heaven for us: heaven is the "inheritance" (Pe1 1:4) given to us as sons, by the promise of God. corruptible--Compare Pe1 1:7, "gold that perisheth," Pe1 1:23. silver and gold--Greek, "or." Compare Peter's own words, Act 3:6 : an undesigned coincidence. redeemed--Gold and silver being liable to corruption themselves, can free no one from spiritual and bodily death; they are therefore of too little value. Contrast Pe1 1:19, Christ's "precious blood." The Israelites were ransomed with half a shekel each, which went towards purchasing the lamb for the daily sacrifice (Exo 30:12-16; compare Num 3:44-51). But the Lamb who redeems the spiritual Israelites does so "without money or price." Devoted by sin to the justice of God, the Church of the first-born is redeemed from sin and the curse with Christ's precious blood (Mat 20:28; Ti1 2:6; Tit 2:14; Rev 5:9). In all these passages there is the idea of substitution, the giving of one for another by way of a ransom or equivalent. Man is "sold under sin" as a slave; shut up under condemnation and the curse. The ransom was, therefore, paid to the righteously incensed Judge, and was accepted as a vicarious satisfaction for our sin by God, inasmuch as it was His own love as well as righteousness which appointed it. An Israelite sold as a bond-servant for debt might be redeemed by one of his brethren. As, therefore, we could not redeem ourselves, Christ assumed our nature in order to become our nearest of kin and brother, and so our God or Redeemer. Holiness is the natural fru…

The apostle describes the persons to whom he writes, and salutes them (Pe1 1:1, Pe1 1:2), blesses God for their regeneration to a lively hope of eternal salvation (Pe1 1:3-5), in the hope of this salvation he shows they had great cause of rejoicing, though for a little while they were in heaviness and affliction, for the trial of their faith, which would produce joy unspeakable and full of glory (Pe1 1:6-9). This is that salvation which the ancient prophets foretold and the angels desire to look into (Pe1 1:10-12). He exhorts them to sobriety and holiness, which he presses from the consideration of the blood of Jesus, the invaluable price of man's redemption (Pe1 1:13-21), and to brotherly love, from the consideration of their regeneration, and the excellency of their spiritual state (Pe1 1:22-25).

1:18 A ransom is paid for the release of a captive. Slaves could sometimes pay a ransom and be released from their master. Christ’s death is the price God paid to release people from captivity to sin (1:19).
