This is for anyone who is called to evangelism but doesn't feel like they are good with speaking to people or don't have that gift of knowing how to word things in a way that will make people understand. The apostle Paul had the same problem, and look how God used him!
In 2 Corinthians 10:10, the people at Corinth were saying of Paul that "His letters are heavy and strong, but his personal presence is unimpressive and his speech is not deserving of respect." Paul's ministry is still getting people saved to this day (about 1,900 years after his death!), and he wasn't even good at speaking to people!
Paul goes on to tell them that they are focused on the wrong things, and that they are looking at the outward things instead of the inward things. It doesn't matter how "entertaining" you are, how creatively you word things, or how clear your speech is. It matters only that you are preaching the truth; let God work the rest out. We can't rely on Earthly things like our ability to speak to bring someone to Christ. According to these verses, if Paul would have lived today, he wouldn't have been one of those preachers who got up and preached a message with power in his voice and worded things in fancy ways to keep people's attention. Instead, he would be more like one of those preachers who stands in front of a church and gives a long message that's full of scripture and truth, but appears "boring". And guess what? That must be pleasing to God, because God is still using Paul to this day!
So, remember today to focus on truth in your evangelism rather than the style, wording, clearness, or ability to entertain. The bible says that those things are worthless.
