All editions of the NIV have given "God's Faithfulness" as the heading for Romans 3:1-8.

========================================================
How do you read "3:1-8"?

1. three one through eight
2. three one to eight
3. three one until eight
4. three one till eight

#1 is correct. This one clearly includes verse 8.

The others could mean 1 through 8 OR 1 through 7, so #1 is the clearest in meaning.
