The last enemy that shall be destroyed is death.
Shall be - Greek (1 Corinthians 15:24), 'is being done away with' (Revelation 20:14; cf. Revelation 1:18). Christ's victory, already won, is earnest of the final 'abolition' of Death; the abolition is being effected continuously up to the consummation (John 5:24; John 6:36). It is to believers especially this applies (1 Corinthians 15:55-57); even to unbelievers death is done away with by the general resurrection. Satan brought in sin, and sin death! So they shall be "destroyed" (rendered utterly powerless) in the same order (1 Corinthians 15:56; Hebrews 2:14; Revelation 20:10; Revelation 20:14).
