The Church As His Ambassador

This sermon was given on Sunday, July 12, 2015 by Todd Olson as part of the sermon series Why Church?.

The Great Commission

And Jesus came and said to them, “All authority in heaven and on earth has been given to Me. Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.” Matthew 28:18-20

The Great Commandment

A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another. By this all people will know that you are My disciples, if you have love for one another. John 13:34-35

A Great Promise

But you will receive power when the Holy Spirit has come upon you, and you will be My witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth. Acts 1:8


A VERY significant book for our purposes in today’s message is “What is the Mission of the Church?” by Kevin DeYoung and Greg Gilbert (Crossway: 2011). Note also “The Deliberate Church” by Mark Dever and Paul Alexander (Crossway: 2005). See chapter 3 on Doing Responsible Evangelism.
