We all have a void in our heart that only God can fill. We go to our children, our spouse, friends, jobs and say fill me.
We walk around smiling like everything is ok when we are dead inside. With our walls of protection and defense are up. When inside we are filled with fear.
Being honest with God about our fears is the place to go. Being real with others soon will come. He calms the waters He can calm your fearful heart.
