1 Corinthians 10:9

Third, the Israelites tested Christ by taxing His patience. The best manuscript evidence suggests that "Christ" rather than "Lord" is the correct word here. If so, Paul again stressed that it was Christ that both the Israelites and the Corinthians were testing (cf. 1 Corinthians 10:4). He made the apostasy in both cases Christological. They dared Him to live up to His promise to discipline them if they doubted His word. They continued to complain even though He faithfully provided for them (Numbers 21:4-9). His provision of manna and water was not adequate from their point of view, and they despised it (Numbers 21:5). The Corinthians had given evidence of being dissatisfied with God’s prohibition of participation in pagan feasts by opposing Paul’s teaching on this point.

Likewise contemporary Christians are in danger of failing to appreciate God’s provisions for them in Christ and despising Him. We can feel dissatisfied rather than thankful and content. Evidence that this attitude existed in the Corinthian church surfaces in 1 Corinthians 1:12 and 1 Corinthians 11:17-34. Perhaps the fact that some of the believers were participating in pagan feasts also indicated dissatisfaction with the Christians’ special feast, the Lord’s Supper.
