First are the grudges against family members, friends and associates. A second grudge may be against God. A third less obvious grudge is against ourselves. Twenty years ago we missed a golden opportunity or failed big time. Twenty years later we still can't forgiven ourselves.
Some grudges are the result of physical and psychological abuse.
Others grudges arise from being misunderstood and marginalized. Some of you have been deceived and betrayed by an unfaithful partner. Others have experienced significant rejection, shame and negative talk. Many people can't put their finger on their precise problem, but this they know, they need a bridge. Others pretend there is no river and we call that denial.
