One thing we talk about a lot in terms of LifeGroups is telling life stories. Something we don't encourage enough is regular or frequent telling stories of what God's doing in your life. Even if it it's just a 2 minute story that BARELY seems significant at all, we SHOULD be in the practice of talking about what God is doing in our lives.
Talk about this idea with your LifeGroup. Give everyone the opportunity to share with the clear understanding that the ONLY acceptable story is --> "I see God doing ________ in my life" or "I was hanging out with God and He told me ________ . "
Talk about creative and good ways that you can start making these statements be a regular part of your discussion with each others.
