correction of your assumption: He speaks to pretty much everyone on the planet. He wants everyone on the planet. The problem is, as is the history of humanity, very few people want to hear what He is saying.
For the record, Muslims do not have a personal god, their god has no declared interest in humanity, and their salvation is on a whim. Humanity exists purely to submit to 'him'. Their god is not my God. At all. Logical really - there are major contradictions between the Christian and the Muslim God - how could they be the same?
