Struggling to lead my family spiritually when I'm not even sure what I believe

My wife has been really pushing for us to get the kids in church and Sunday school. She wants me to be the spiritual leader of our family which is a lot of pressure. The thing is I grew up in the church but walked away in my 20s and I'm still figuring out my own faith. I don't want to be a hypocrite teaching my kids about God when I'm still wrestling with doubts myself. How do you lead by example when you're not sure what you believe? Has anyone else been in this spot?
