Passage
For since by man [came] death, by man also resurrection of [those that are] dead.
For since by man [came] death, by man also resurrection of [those that are] dead.
1 Corinthians 15:19 If in this life only we have hope in Christ, we are [the] most miserable of all men.
1 Corinthians 15:20 (But now Christ is raised from among [the] dead, first-fruits of those fallen asleep.
1 Corinthians 15:21 For since by man [came] death, by man also resurrection of [those that are] dead.
1 Corinthians 15:22 For as in the Adam all die, thus also in the Christ all shall be made alive.
1 Corinthians 15:23 But each in his own rank: [the] first-fruits, Christ; then those that are the Christ's at his coming.
The verse centers on "since", "came", "death", "resurrection", and "dead". It is saying that the verse draws attention to "since" and "came", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 20's "But now Christ is raised from among..." into verse 22's "For as in the Adam all die...", so "since" and "came" belong inside that flow. In 1 Corinthians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "since" and "came" with trust shaped by these words, not by a vague optimism outside the passage.
