The purpose of life is to Experience, to Learn, to become more loving and caring of others that we may spiritually GROW
Life is a gift. We should be thankful for each new day. We should appreciate and be thankful for what we have, and not waste our lives in regret over what we don't have.
Does God exist? God supports everything good on this Earth every second of every day with unseen energy. This energy comes through from the true reality of Heaven, the "Spiritual" dimension that exists alongside our physical universe, and from which our physical universe was created.
When we die, we do not cease to exist. We simply pass through a door into Heaven the "Other side Of Life" We return to our familiar home where we lived before this life.
There are many people who are totally self-centred - they only think about themselves, and they only show interest in someone else if they want something! The problem with self-centred begaviour is that it can hurt people, either emotionally, psycholigally or even physically. These people have lots of what we call "Negative Energy".
Years of building up love and trust can be destroyed in seconds by simple words such as "I hate you". Negative energy comes quickly, often unexpectedly, and the damage it causes can last weeks/months or years.
More advanced souls who are loving and caring and self-sacrifice often with little recognition. They won't walk over other people so often don't achieve political power, wealth or fame.
Earth is a very beautiful place, and there is much love and a constant monitoring from Heaven of life and nature, and concern over the destructive forces at work. God influences people to fufil certain positive roles on Earth. Some may feel an overwhelming calling to campaign to protect nature and the environment. Others to help those who are sick and disabled. Others to feed the hungry. I cannot comment on political "callings". Some are driven by the desire for power, some by ideology, and some by genuine concern to try to do some good.
None of us are perfect. We all make mistakes. All that God expects of us is to try our best to get things right, to try to help others, and when things go wrong think about any lessons that we can learn.
No matter what goes wrong we should never put our lives on hold unless our liberty is taken from us by others. Life is a gift and we have a duty to fulfil our life's purpose no matter how insignificant it may seem to others.
