Watch how a waiter comes to your table at a restaurant. When he interrupts your conversation and asks if you are ready to order, you don't say, "Excuse me! I was talking with my friend and you butted in. You are very rude!" This is because he has something that you want. Food. That's why he is confident. We have something that the world wants. Everlasting life. There is a cry within the heart of every sane human being that says, "I don't want to die!" And it's that knowledge that gives us our confidence. Notice what happens if a new waiter is shy. He is put with an experienced waiter, and when he sees that people aren't offended when he butts in, his confidence builds. So, go with an experienced waiter. Watch Paul's boldness in Romans 2, or watch Jesus in Mark 10, and watch your own confidence grow. There goes another minute. Gone forever. Go share your faith while you still have time.
