The Driving force is your conscious/ness. God is within you/us. Upon Self Realisation, the almighty will be Visualised. To acquire that state, constant meditation, purification of mind and body are pre requisites.
God is everywhere but we can't see him.If u believe in him, then u can see him. Sometimes when u are in a doubt or when u are going to do a wrong thing, we get a feeling of it.He always guides u and it is us who have to decide to follow him or evil.
