To Impact Community

After serving in the church for almost ten years now, I have been reflecting my impactor influence and have to conclude that I did not impact any body to the community beside the church members - beyond four walls where I serve.
We Christians claimed to be the salt and light of the world. But then I did not impact at all to the world. If I claim to be salt and light, there must be some kind of impact to the community, the society I live in.
My prayer is to impact the community, to bless the community, to see there is some changes in the society. I want to see that they see the light of Christ in me...
