You will continue to be effected by them until you heal the problems in your past lives or in past events from your present life that caused them to become part of your being. The truth is that each has a place in God's universe and each has a role to play. At one time, we have or will have all played all the roles. For example, Romans come back as barbarians, Arabs come back as Israelis, Chinese come back as Japanese, whites come back as blacks, men come back as women, and so on until as Soul we can tolerate and embrace all ways of being. And yet since our bodies were made to give and receive unconditional love, carrying negative emotions like intolerance and unforgiveness will cause us pain.
Hate is THE most difficult resonance of all to heal.
What eventually stops hate is the heavy price it carries as we make our long journey as Soul. Hating is like taking poison and expecting someone else to die because what you wish for others is what you will attract to yourself. For until you can fully embrace what it is that you hate, you will never fully share in God's love. For all that exist are created by God to serve his purposes in the unfolding majesty of His Creation. And the list goes on and on seemingly forever.
