1 Corinthians 10 v 5


1 Corinthians 10:5 
But with many of them God was not well pleased: for they were overthrown in the wilderness. 


10:5. The presence of supernatural privileges in the lives of Old Testament Israelites did not produce automatic success. On the contrary, in spite of their special advantages, most of them (in fact, all but two members of one generation, Joshua and Caleb) experienced God’s discipline, were disqualified, and died in the desert (Num. 14:29). In light of this, Paul’s avowed need for personal self-discipline (1 Cor. 9:27) was genuine since even Moses was disqualified for the prize (Num. 20:12).
