Here is the link to the article where the comments were made.
"...thinking that they needed to avoid politics and that is so wrong because God is the one who chooses our rulers. And if we are the ones not actively involved in electing those godly men and women and if people aren’t involved in helping godly men in getting elected than we’re going to have a nation of secular laws. That’s not what our founding fathers intended and that’s certainly isn’t what God intended"
