Thanks for posting this Derek? Not sure who is responsible for posting this but we love listening to Tim's vast knowledge and he is such a nice dude too!
Also thank you for the other video posted, we were so happy to see and hear what they had to say (the one with Raavi Z and RC Sproul) we couldn't agree more with what they have to say. We wish we weren't "old" folks, so we could attend the YA group it sounds like you guys are doing some interesting stuff this year.
May God bless you guys as you seek to do what you are doing.
Anita and Craig
