The area of our lives that the devil is most easily able to gain a foothold… is when we have unforgiveness in our hearts.  II Corinthians 2:10-11 tells us that we need to forgive in order that Satan might not outwit  us.  When we harbor unforgiveness, we allow the devil to capture a place in our heart…setting up a position – a base of operations for further advancement against us.   We need to remain then vigilant…forgiving and forgetting quickly, so as not to allow him the ability to take advantage over us.
