Dr. Stanley used Matthew 28:16-20, often referred to the "Great Commission," a passage where Jesus instructs his disciples and all of us to tell others about Jesus and call them to become disciples.
In the message, Dr. Stanley made a good point that many people don't really know who Jesus is, and therefore don't understand Him. They may have an impression of Jesus based on faulty assumptions. It is our responsibility, once saved, to tell others about Jesus. We don't have to do this alone, said Dr. Stanley, as the Holy Spirit is available to help us say the right things.
Stanley also pointed out that we don't need special technology to spread the Gospel as word of mouth is typically used to tell others about Christ. I agree with his point, but value the Internet as I hope to use it as a tool to spread the Gospel to the uttermost parts of the world just as Jesus told us to do as recorded in Acts 1:4-8.
An outline of Dr. Stanley's sermon can be found online at his InTouch.org site as well as a Bible study lesson on the topic and you can listen (Jan. 21-22) or watch his Sunday, Jan. 20, 2008 sermon as well.
Have a blessed day by telling someone about what Jesus has done for you.
Your Brother in Christ,
