Destiny Happens, we reap what we sow in the end

I have always believed in fate, and certainly over the years I have learned that whatever we put out to the universe comes back to us threefold. If you give out negative energy to the universe, you will get that back to you over and over again until you learn lessons in life and learn that the way to manifest good karma in your life is to learn that only goodwill generates goodwill.
I have learned some harsh lessons in life in my early 20s and lost some friends along the way who were only around for a good time and disappeared when times got challengibg or rough. If you dont learn these lessons then destiny will get you in the end.
I have a strong faith in God and believe that God will be loving and merciful to you provided you have been loving and kind to you, but if you have manifested nasty attitudes and beliefs and actions God will be judgemental towards you. So beware as we all reap what we so in the end and I want to manifest a good hand in fate/destiny?
