It's been a couple of years since we did LHFHG and my memory isn't what it used to be so my details are sketchy. I do remember though that we had some really thoughtful discussions during that time. So much of the curriculum is based on the Bible that we were talking about how everything related to the Bible most of the time. LHFHG especially is based on Biblical history so it gives lots of time to discuss how God has directed history and what His ultimate plan for man is. It was a wonderful year for us and sparked a wonderful communication between my dc and me about God.
We haven't done Preparing yet, that is on schedule for this fall, but we are currently doing Bigger and loving the Bible component of the program. Like the other HOD programs that we've done, it has Bible woven throughout, but the thing that I love so much about Bigger is the character trait study. Each week we are studying a character trait based on our scripture memory verse. It has been so wonderful studying these character traits and seeing how the historical characters displayed these traits as well as how Biblical characters displayed these traits. We are also getting more Biblical character training through DITHR so this has been a great character building year for us all!
All of the HOD programs we have used so far have focused our attention towards God in more than just the Bible study portion of the program. I think you'll find there is more to it than just the Bible study box. You'll find it in the history, the science, the grammar, the poetry, the music, pretty much everything except math. If when you are doing it though, you feel you want to dig deeper, there is time for that. The HOD curriculum is compact enough to easily be done in 1/2 day, especially LHFHG which will only be about 1 1/2 hours, so you will have plenty of time to continue doing the Bible study you are currently doing if you choose.
