God, yourself, and others.

Love God, love yourself, then you will be able to love others.
First and foremost love your God (whatever God is to you), clean your Spirit which leads to loving yourself. For without loving who you are (in side) and loving what you believe to be the real you, you can not start the journey of loving others.
I know this not because I am smart or because I have all or any of the answers but, I have learned this from my God.
Be at peace with God, then with yourself and then peace and love will come from within with ease.
