I am he that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and of death.

People's New Testament

1:18 He that liveth, and was dead. Put to death but living.

And have the keys of hell and of death. The keys of death and of Hades (Revised Version). Not only a victor over death, but the very gates of death and Hades are under his control. Hence he can deliver from the dead whom he will.

Wesley's Notes

1:18 And he that liveth - Another peculiar title of God. And I have the keys of death and of hades - That is, the invisible world. In the intermediate state, the body abides in death, the soul in hades. Christ hath the keys of, that is, the power over, both; killing or quickening of the body, and disposing of the soul, as it pleaseth him. He gave St. Peter the keys of the kingdom of heaven; but not the keys of death or of hades. How comes then his supposed successor at Rome by the keys of purgatory? From the preceding description, mostly, are taken the titles given to Christ in the following letters, particularly the four first.

Jamieson-Fausset-Brown Bible Commentary

18. Translate as Greek, "And THE Living One": connected with last sentence, Re 1:17.

and was-Greek, "and (yet) I became."

alive for evermore-Greek, "living unto the ages of ages": not merely "I live," but I have life, and am the source of it to My people. "To Him belongs absolute being, as contrasted with the relative being of the creature; others may share, He only hath immortality: being in essence, not by mere participation, immortal" [Theodoret in Trench]. One oldest manuscript, with English Version, reads Amen." Two others, and most of the oldest versions and Fathers, omit it. His having passed through death as one of us, and now living in the infinite plenitude of life, reassures His people, since through Him death is the gate of resurrection to eternal life.

have . keys of hell-Greek, "Hades"; Hebrew, "Sheol." "Hell" in the sense, the place of torment, answers to a different Greek word, namely, Gehenna. I can release from the unseen world of spirits and from DEATH whom I will. The oldest manuscripts read by transposition, "Death and Hades," or Hell." It is death (which came in by sin, robbing man of his immortal birthright, Ro 5:12) that peoples Hades, and therefore should stand first in order. Keys are emblems of authority, opening and shutting at will "the gates of Hades" (Ps 9:13, 14; Isa 38:10; Mt 16:18).

Matthew Henry's Concise Commentary

1:12-20 The churches receive their light from Christ and the gospel, and hold it forth to others. They are golden candlesticks; they should be precious and pure; not only the ministers, but the members of the churches; their light should so shine before men, as to engage others to give glory to God. And the apostle saw as though of the Lord Jesus Christ appeared in the midst of the golden candlesticks. He is with his churches always, to the end of the world, filling them with light, and life, and love. He was clothed with a robe down to the feet, perhaps representing his righteousness and priesthood, as Mediator. This vest was girt with a golden girdle, which may denote how precious are his love and affection for his people. His head and hairs white like wool and as snow, may signify his majesty, purity, and eternity. His eyes as a flame of fire, may represent his knowledge of the secrets of all hearts, and of the most distant events. His feet like fine brass burning in a furnace, may denote the firmness of his appointments, and the excellence of his proceedings. His voice as the sound of many waters, may represent the power of his word, to remove or to destroy. The seven stars were emblems of the ministers of the seven churches to which the apostle was ordered to write, and whom Christ upheld and directed. The sword represented his justice, and his word, piercing to the dividing asunder of soul and spirit, Heb 4:12. His countenance was like the sun, when it shines clearly and powerfully; its strength too bright and dazzling for mortal eyes to behold. The apostle was overpowered with the greatness of the lustre and glory in which Christ appeared. We may well be contented to walk by faith, while here upon earth. The Lord Jesus spake words of comfort; Fear not. Words of instruction; telling who thus appeared. And his Divine nature; the First and the Last. His former sufferings; I was dead: the very same whom his disciples saw upon the cross. His resurrection and life; I have conquered death, and am partaker of endless life. His office and authority; sovereign dominion in and over the invisible world, as the Judge of all, from whose sentence there is no appeal. Let us listen to the voice of Christ, and receive the tokens of his love, for what can he withhold from those for whose sins he has died? May we then obey his word, and give up ourselves wholly to him who directs all things aright.
