who by the power of God are guarded through faith for a salvation ready to be revealed in the last time.
through faith unto salvation: This word "faith" means "a strong and welcome conviction of belief that Jesus is the Messiah, through whom we obtain eternal salvation in the kingdom of God" (Thayer 513-1-4102). This same word is used three times in this chapter (in verses 5,7,9). Peter here emphasizes the "human factor" in our salvation. It is not imposed upon us, nor is it a salvation that cannot be affected by the lives we live; rather, our salvation depends upon our faith. If we are "faithful until death," we shall receive the "crown of life" (Revelation 2:10).
