Ive been thinking about (Romans 1:20 For since the creation of the world God's invisible qualities--his eternal power and divine nature--have been clearly seen, being understood from what has been made, so that people are without excuse.) and feel that I have quite a deep or complexed understanding of that statement after what I believe is some sort of revelation that came to me...
I believe that the bible is the word of God, that the bible is some sort of message or information about God that he wants us to know, about him and who he is, but after really indulging in Romans 1v20 in particular, ive come to understand and belive that not only by the word God we know who he is but by all things that he made. In Genesis 1:26 the bible says God created man in their image, with their likeness... so my understanding is that humans have the same emotional makeup as God, we need and long for the things God does(I'm not saying God is in need of anything) we have a sense of being loved like he does, we feel sad, we have a sense of a need for fellowship and having relationships, we create and repair just like him, in his likeness just to name a few. So basically what I believe is that looking at humans we can have an idea of how God is, emotionally and spirituality. The same goes with Romans 1:26, we can further know who God is and his nature by looking at everything that he created. Everything from the birds in the sky, how they live and how they die...to the plants that grow, the way they are uniquely made with an instinctive character can all help us understand the nature of God.
