1 Corinthians 10:5

But with many of them God was not well pleased: for they were overthrown in the wilderness (KJV)

Then: It had to have been a sobering thought that the Lord who gave water to the Israelites became angry with them. At what point and in what ways could he become angry with the Corinthians? Paul is telling them, "Be careful. Don't let it happen to you. Consider your actions." Belonging to the Messiah is not a casual affair (Wright, p. 125).

Now: "Wake-up" calls are a blessing to those who receive them. Following Christ in today's hedonistic, materiarlist world can be just as confusing to us as it was to those living for Christ in Corinth. Paul's words bless us and his love for the Corinthians blessed them.
