Passage
for since through man <FI>is<Fi> the death, also through man <FI>is<Fi> a rising again of the dead,
for since through man <FI>is<Fi> the death, also through man <FI>is<Fi> a rising again of the dead,
1 Corinthians 15:19 if in this life we have hope in Christ only, of all men we are most to be pitied.
1 Corinthians 15:20 And now, Christ hath risen out of the dead--the first-fruits of those sleeping he became,
1 Corinthians 15:21 for since through man <FI>is<Fi> the death, also through man <FI>is<Fi> a rising again of the dead,
1 Corinthians 15:22 for even as in Adam all die, so also in the Christ all shall be made alive,
1 Corinthians 15:23 and each in his proper order, a first-fruit Christ, afterwards those who are the Christ's, in his presence,
The verse centers on "since", "through", "death", "rising", "again", and "dead". It is saying that the verse draws attention to "since" and "through", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 20's "And now Christ hath risen out of..." into verse 22's "for even as in Adam all die...", so "since" and "through" 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 "through" with trust shaped by these words, not by a vague optimism outside the passage.
