Heb 3:12-14
Make sure there's no evil unbelief lying around that will trip you up and throw you off course, diverting you from the living God. 13 For as long as it's still God's Today, keep each other on your toes so sin doesn't slow down your reflexes. 14 If we can only keep our grip on the sure thing we started out with, we're in this with Christ for the long haul.
