We believe that, at the return of Jesus Christ, the righteous dead will be resurrected in an immortal state and, together with the living saints, will be translated by the Lord Jesus.
1 Thessalonians 4:13-18 – But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope. For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him. For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep. For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord. Wherefore comfort one another with these words.
Romans 6:5 – For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection.
1 Corinthians 15:51-53 – Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed, In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed. For this corruptible must put on incorruption, and this mortal must put on immortality.
Revelation 20:6 – Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.

The wicked will be resurrected a thousand years later to receive their final judgment.
Revelation 20:5, first part – But the rest of the dead lived not again until the thousand years were finished…
