...I am trying to be more perceptive about those around me with whom the Lord seems to be giving me an 'in.' I can have substantive conversations about world-view issues with two of the scientists I work with, and I appear to be gaining an 'in' also with our building security guard, a Jehovah's Witness who used to play keyboards with a very famous pop star!

In addition, as I wrote in another reply, my church has quite a few Visiting Scholars from China who attend, and potentially they are leaders back in their own country, who might have a disproportionate influence if they come to faith in Jesus before returning to their own country. I very much enjoy their company, but also am always hoping to begin an evangelistic Bible study with a small group of them. (Only had success once with that, so far.)

Kevin -- Great suggestions! There is no doubt to me that each has a tremendous potential for kingdom impact. A couple more that occurred to me are: 1) becoming a mentor to someone, especially someone in the younger generation, and given the correlation of illiteracy and incarceration, 2) teaching a child to read.

Several come to mind, and I think that from my limited perspective I cannot tell which would have a more substantial impact, but:
-- intercessory prayer for my pastor, church leadership, church community, and greater community
-- a more earnest pursuit of personal holiness
-- a more one-minded pursuit of God
