I agree with Dis-member, if he really loved us as a heavenly Father, he would make an effort to be more present in our lives. All the physical provisions like air, food, water, sunshine, etc can't compensate for his absence. A truly loving Father is present in the lives of his children and does not just give material provisions to make up for his absence.
He would also be a much better communicator. What loving father writes a letter to his children in a cryptic way to make it diffcult for them to understand and easy for it to be interepreted in multiple conflicting ways, leading to confusion? But then again, the confusion created by the bible probably speaks more to his incompetence as an author than his lack of love.
