When you say "I look for God in the hearts of people like Dale Lang and I find Him there. I look for God in the hearts of people like Jean Vanier and I find Him there. I look for God in human activities such as the Truth and Reconciliation Commission..." you are speaking poetically, not literally.
The fact that people may do good is not evidence that there is a deity.
When you write "I believe that God works through the hearts of humans and I find that confirmed by the actions of people who live out lives of altruistic sacrificial love of others" you only demonstrate that you believe there are people who act in altruistic ways. That is not a demonstration of why one out to believe that there is another entity behind such people.
You're putting the cart before the horse. If you think intelligence has to exist before life itself can exist (because you think life has to be "created" by an "intelligence") then you're postulating that an intelligent agency can develop out of some kind of natural origin without the need for life to exist first!
But this means you think that something even more extraordinary than just "life" (that is, "intelligence") can develop naturally. So you must also concede it is even more likely that life can develop naturally.
