Anyone who tries to teach another person the gospel is a successful personal evangelist. Anyone who does their best to get a fellow human being to accept God’s word and obey it is a success in God’s eyes. “Stephen, do you mean that even if I don’t convert anyone, but if I’m out sowing the seed, then I’m successful?” That’s right. We don’t measure success in evangelism by the number of conversions (or at least we shouldn’t). We can’t make anyone respond to the plan of salvation, but we must give them the opportunity to obey it. Yes, we want them to obey since that is the desired result, but we are successful if we faithfully teach the word to others in an effort to get them to respond to it. Don’t ever forget that!
