Passage
And all drank the same spiritual drink: (And they drank of the spiritual rock that followed them: and the rock was Christ.)
And all drank the same spiritual drink: (And they drank of the spiritual rock that followed them: and the rock was Christ.)
1 Corinthians 10:2 And all in Moses were baptized, in the cloud and in the sea:
1 Corinthians 10:3 And did all eat the same spiritual food:
1 Corinthians 10:4 And all drank the same spiritual drink: (And they drank of the spiritual rock that followed them: and the rock was Christ.)
1 Corinthians 10:5 But with most of them God was not well pleased: for they were overthrown in the desert.
1 Corinthians 10:6 Now these things were done in a figure of us, that we should not covet evil things, as they also coveted.
The verse centers on "Spirit", "drank", "same", "spiritual", "drink", "rock", and "followed". It is saying that the verse draws attention to "Spirit" and "drank", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 3's "And did all eat the same spiritual..." into verse 5's "But with most of them God was...", so "Spirit" and "drank" 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 "Spirit" and "drank" with trust shaped by these words, not by a vague optimism outside the passage.
