J.H. Bavinck:

As long as he is occupied with himself only and looks no further, he can fancy himself to be self-sufficient. But as soon as he becomes aware of his relationships, he becomes stupefied, and asks: What am I in this great cosmos? What am I over and against the norm, that strange phenomenon in my life that has authority over me? What am I in my life that speeds on and on–a doer or a victim? What am I in the face of that remarkable feeling that overwhelms me sometimes, that feeling that everything must change and that things are not right as they are? What am I over against that very mysterious background of existence, the divine powers? It is in this area of existential relations that man is confronted with the crucial matters of life–and one of these is religion. Religion convinces man that there are relations. It reveals the ‘seams’ of creation where one thing is connected with another. We can now give the following definition of religion: Religion is the way in which man experiences the deepest existential relations and gives expression to this experience.
