Does anyone have any tips for bathing an abused Golden Retriever?

We recently adopted a golden retriever that was severly abused. Goldens usually love the water, but he does not due to the way his abusive parents bathed him. So far he is very friendly when he is sitting down and is accepting to petting and touch. However, when he is standing, he will scurry from you if you get too close. We have only had him for a week so we expect him to be scared of us, but does anyone have any tips for bathing and also any on how to break that fear barrier that causes him to scurry from us? Thanks
