Passage
and all drank the same spiritual drink, for they drank of a spiritual rock which followed [them]: (now the rock was the Christ;)
and all drank the same spiritual drink, for they drank of a spiritual rock which followed [them]: (now the rock was the Christ;)
1 Corinthians 10:2 and all were baptised unto Moses in the cloud and in the sea;
1 Corinthians 10:3 and all ate the same spiritual food,
1 Corinthians 10:4 and all drank the same spiritual drink, for they drank of a spiritual rock which followed [them]: (now the rock was the Christ;)
1 Corinthians 10:5 yet God was not pleased with the most of them, for they were strewed in the desert.
1 Corinthians 10:6 But these things happened [as] types of us, that we should not be lusters after evil things, as they also lusted.
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 all ate the same spiritual food..." into verse 5's "yet God was not pleased with the...", 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.
