Sometimes God calms the storm and sometimes He lets the storm rage and calms His child

this is an amazing quote that I find so hard to understand but know that it is the right way for me to feel.  I am struggling with every facet of my life when I am constantly angry with a person and feel bitter toward this person who is always around. I am trying to let it go and give it to God and hoping He takes it away and there it is in my face and constantly digging a new home each day.  it is a constant struggle and I need to rededicate it to God every 20 minutes if not sooner.
