Paul shows how the community of Israel, established by God and given gifts by God, still sinned and was judged. Because of that, it gives the Christians in Corinth an example, and us as well, of what not to do. Dependence on God and his faithfulness, not on us, our abilities or experiences, will help us endure temptation, defeat sin, and live the life Jesus has set out for us.
This is the audio podcast from Bert's sermon at Anthem Camarillo.
