When your heart grows cold toward God, it's usually reflected in a loss of spiritual vitality. And like Samson (in Judges 16:20),  you're not even aware of it. You dread praying. You're no longer a godly influence on those around you. You slip into old bad habits. You refuse to forgive. You're easily offended. You fail to make amends to those you've hurt. These are the 'little foxes' that destroy your vine and undermine your relationship with God. You need a spiritual overhaul. Now, ask God to highlight those attitudes, activities and relationships that need to be dealt with - then weed them out!
