On 10 in 2 - thoughts about some Christian goal setting

Just read this article in my latest copy of the briefing. (It seems most parts of the "Up Front" section of the Briefing have appeared previously on the blog solapanel.org.)
In the "10 In 2" article, Ben Pfahlert talks about his goal of trying to reach 10 people in 2 years with the gospel.
I have previously read of similar goals taken on by "trainees" - but that was talking about China! (see Brother Yun "The Heavenly Man"). I think they had a much high target, but they were going on a full time mission so that might be expected.

I think this general idea is good. Whether others make this commitment or a similar one is good.

Of course, a necessary factor is our dependence on God. God gives the results. It is God who draws people to himself. But on the other hand, not to plan, not to dream for God's Kingdom probably means that we are complacent or love this life too much, and possible have the wrong sort of dreams.

But is making plans like this risky? Should we aim at things we can't control?
Two points:
(1) John Piper, arguing against the idea that God is a risk taker, says that we can be risk takers because God isn't. God is in control, he has our future in his hands, so what do we have to loose? We can only gain. If we loose friends and money in the process, then we haven't lost anything in eternal terms (c.f. 1 Cor 15). On the other hand we will be gaining "friends for life" - eternal life that is.
(2) Even though we can't control the out come, we have been given this mission anyway (Matt 28:18-20). But we need to say more. Some one has said "Failing to plan is planning to fail". Making goals and plans and praying about them helps us to focus, and be diligent. Yes, God can use us in unexpected ways, and despite our efforts, and using it all to teach us hard lessons. We might find there are hard lessons we need to learn before we can really go on with our plans. But these are not points against it. Paul made plans and was deliberate about using his time and energy for the gospel.

I have been forming plans in the back of my head, especially after using the "Christianity Explained" course. Maybe I should commit instead of letting them just float around.
