1 Corinthian 10:3

And did all eat the same spiritual meat (KJV)

Then: This is a "Yikes!" verse. What is Paul doing? He took the Corinthians right back to the problem of eating meat associated with religious beliefs. God provided food (manna and water in the desert - bread and wine at the last supper). They had just bought into the comparison of the two baptisms, so cannot now back out of the second analogy. Baptism and Communion (Wright, p. 123). The conjunction of God's work in the Old Testament and his continued work in the New Testament (Thistleton, p. 718) is a signatory highlight of Paul's mind and of all believers. Just as the Israelites could anger the Lord by complaining about the food, the Corinthians could anger the Lord by carelessly eating at both the communion table and in idolatrous temples. Those who live in two worlds put their salvation at risk (Wright, p. 124). They may slide backwards away from Christ. If the Corinthians will just think about their fathers (verse 10:1) and the spiritual rock which provides living water, they will have the knowledge to control their behaviors and not lose their salvation.

Now: A common term today is "Sunday Christians." Usually it is applied to everyone else and never personally. If however, Paul who had such a close relationship with Christ feared losing his secure place, should not the rest of us treat our daily choices much more carefully? They may not involve temple meat, but there are 1001 ways to live a double life - and not even know it. Prayer, enlightenment, and confession need to occupy more of our day.
