If it were easy being a good dad, everyone would be doing it.
Noah qualifies as a good dad. I think you could put him in the great dad category.
That begs the question, "What defines a great dad?"
Here's my answer based on what I know of the Bible and from what I see of Noah:
1) He pleased God.
That's what it means to find "favor" with God. He was a great earthly father because he pleased his Heavenly Father. How? By being "righteous, blameless and walked with God".
2) He prayed
Where does it say that? How did he know about building the ark? God gave Noah a detailed description on how to build something he had never seen before - a boat!
3) He perservered
For over 100 years he worked on constructing the ark. Every day for more than a century he got up and went to work on this ship of salvation.
4) He protected his family
Obviously, he delivered his family from the flood waters, but more importantly, he protected them spiritually from the moral corruption of that day.
5) He provided for his family.
As a responsible bread-winner, Noah made sure his wife and children had what they needed.
Noah is in the Hall of Faith listed in Hebrews 11. Rightly so! But he also ranks high on the Hall of Fathers. He became a great father by pleasing His Heavenly Father!
How about you? Have you found favor with God? Are you pleasing your Heavenly father by being righteous, by being blamesless, and by walking with Him?
