Noah possessed three qualities that enabled him to provide spiritual protection for his family.
1. Righteousness (6:9)
A. He had personal righteousness (he himself lived a righteous life).
B. He had public righteousness (he was righteous in the midst of an unrighteous society).
C. He had pure righteousness (he "walked with God").
2. Readiness (6:10-7:5)
Matthew 7:24-25
A. He was ready to obey even when he didn’t understand it all (had never seen it rain; did not know what an ark was; etc.).
B. He was ready to obey even the smallest detail (note the precise instructions of the ark).
3. Reverence (8:18-21a)
A. Noah’s worship was God-centered (he "built an altar to the Lord").
B. Noah’s worship was sacrifical (he offered an animal when there weren’t many animals around).
C. Noah’s worship was God-pleasing (his sacrifice was a "pleasing aroma" to God).
