1) Verse 16 underscores that faith is the cornerstone. Our actions in the kingdom are driven by our faith. Faith is the initiator, and the fruits of that faith follow. Faith is the seed, and the works are the fruits that sprout from this seed. Everything begins with faith. It's the only way to please God, and it's what He expects from His children.

2) Verses 16 and 17 further elucidate that God's promises are a free gift, but they must be accepted, and faith is the medium for acceptance. It's not about adhering to the law; it's about trusting God. It's not merely about believing in God; it's about believing God. Because Abraham trusted God, he became the father of many nations. Because Abraham trusted God, the dead were resurrected. That which didn't exist before now exists, all through the medium of faith. Remember, this is written for our edification.

3) David pulls out a new element as he quotes seven top tier people of faith, regarding their take on faith. Each ion has a seed of blessing connected to it. So, yep, the list is pretty cool.
