"Who verily was foreordained before the foundation of the world, but was manifest in these last times for you." 1 Peter 1:20
By "these last times" is meant this present dispensation, the dispensation of grace under which we live, and they are called the last times chiefly for two reasons:
1. Because Christ was manifested in the last days of the legal dispensation of the old covenant, which now, as decaying and waxing old, was ready to vanish away (Heb. 8:13), which it did when at the destruction of Jerusalem the whole of the temple service, including the sacrifices offered there, was brought to an end.
But 2. Another reason why the dispensation under which we live is called "the last days" is because it is the final revelation of God. It is "the time accepted," "the day of salvation," of which all the prophets have spoken (2 Cor. 6:2; Acts 3:24). Christ is now upon his throne of grace; the great, the glorious, the only Mediator between God and men is now at the right hand of the Father; the Intercessor who is able to save to the uttermost all that come unto God by him, seeing he ever liveth to make intercession for them, still lives to plead, as an Advocate with the Father, Jesus Christ the righteous, as the great High Priest over the house of God. But he will leave the throne of grace to take his seat on the throne of judgment; and then "these last days" will close in all the glories of salvation to his friends, in all the horrors of destruction to his foes.
