I get what you are saying. I think an offering is great. But for me I guess I personally feel giving back to your kin so to speak is a lot stronger. Doing things for others KWIM? But then I don't follow any deities as such, my spiritual beliefs are separate from any gods iykwim? But it's not until recently that I've looked at things from the perspective of "what do I do?". I guess this is where I believe similarly to christians.

I've always felt that Karma extends more than doing unto others. I try and keep my thoughts in line with this too. And whilst I don't do things to even the balance, I do try and live my life as selflessly, without being a martyr, as I can.
