God Defines Love
The sad truth is that, naturally, human beings do not love God - the person who made them, sustains them, provides for them and heaps goodness upon them. We are all sinful from birth (Psalm 51:5): that is, we resist the authority of God and express that rebellion in a million different ways which we call 'sins'. It is not that we have wandered from perfection: we start in imperfection and daily deface the glory of God (Romans 3:23).
