Here Scripture makes one its most extravagant promises. Time spent building a healthy marriage comes back to us in the effect upon our children, and upon the generations beyond. The geometric principle also applies to our witnessing for Christ. While we should be alert to every opportunity to tell others about him, in the long run the quality of our interaction with people has far greater impact than the number of people to whom we witness. Some find they can persuade many to accept Christ through an evangelistic method or routine.
Evangelistic methods can be of value in some cases.
Yet when we become too concerned with goals or quotas in witnessing, the conversions that result are often superficial, and don't hold firm over time. We are usually most effective for Christ spending our time building solid relationships with a few people, with whom we share our faith naturally. It is important for us to think geometrically about our professional life and other roles as well. Over time, it's the excellence of what we do rather than the quantity of our output that makes the greatest impact. While our job may not allow us the luxury of emphasizing quality over quantity, there are often golden opportunities outside of our professional work for doing so, where we can use our best gifts and meet critical needs of people.
