Talk About God...Often!
"So commit yourselves wholeheartedly to these words of mine. Tie them to your hands and wear them on your forehead as reminders. Teach them to your children. Talk about them when you are at home when you are on the road, when you are going to bed and when you are getting up."
God made it very clear to His people that they needed constant reminders of His truth, that they needed to talk about it with others and talk about it wherever they were. This doesn't mean you have to preach a sermon to everyone you see, but it does mean faith should come up from time to time. Be ready to talk about what God has done in your life.
