What a fun and enlightening topic ...
I like Jedediah because the story of David and Solomon is so intense. I really like the story because it shows how messed up humanity is but yet how God has plans for us, and how the condition of our Heart is the focus not our past mistakes. I like David because of his heart but he did some pretty messed up stuff, none the less I can't use David because then my son would be like D23 or something, no offense but your namesake is rich with history but rightly well used ... I can't use Solomon because although I desire wisdom for my Son, it is clear from that story that all of the Wisdom man can obtain does not lead to happiness or a kind and soft heart. That is why I like Jedediah, in the midst of this crazy story, an child is born, conceived by what could be called pretty evil behavior (being murder and adultery), but God see's this little one and despite knowing his future and past still names him Jedediah, "loved by the lord". I think that is pretty cool.
