A "key," in the symbolisms of the Scriptures, is representative of the opening power vested in the one who has been duly authorized to act, just as is sometimes expressed in the vernacular–"He holds the key to the situation." St. Peter was given two "keys" (`Mat. 16:19`), one of which he used on the day of Pentecost when he opened the way for the Jews to enter into the Kingdom by preaching the Gospel of Christ and the Kingdom (`Acts 2:22-36`.) Three thousand Jews entered in though this opened door (`verse 41`) on that very day. The second key was used three and one-half years later when St Peter opened up the way for the Gentiles to enter into the Kingdom, by preaching the Gospel to Cornelius who accepting the message, and believing, became the first Gentile convert to Christianity. (`Acts 10:44,45`.) In `Rev. 1:18` the glorified Savior is represented as speaking, saying "I am He that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and death." The Lord Jesus, by virtue of His death and resurrection, accomplished the redemption of the race of mankind from death and hell– hades, the grave. Because He thus bought the race, He has the "keys," the opening power, to release all mankind from the great prison house of death and the tomb, as we read concerning the Lord Jesus–"The Spirit of the Lord God is upon me; because the Lord hath anointed me…to proclaim liberty to the captives, and the opening of the prison to them that are bound." `Isa. 61:1`.
