You cannot hate God and love people, neither can you love God and hate people! You see, the issue is not the object if your love or hate but the STATE OF YOUR BEING!
A heart full of hate – it does not matter what the object is – becomes poisonous and forgets the language of love. The reverse is also true, a heart full of love radiates the fragrance of love and forgets the language of hate.
So forget about God or the Devil and others and concentrate of the state of your heart. What you are is what will always come out of you. Religious affiliation, your faith, your ideologies and philosophies don’t change whom you are basically.
I have gotten a lot of love from sworn atheists and non believers and I have experienced horrible hatred from faithful churchgoers and the so called religious people.
