John the Baptist's mission was to prepare the way for Jesus. His mission was to call people to repent and turn back to God. His mission was to point people to Jesus.
That is our mission today. Jesus tells us to "make disciples of all people." He gives us the Holy Spirit so that we can be witnesses for Him. Our mission is "Connecting People to Jesus." That may mean calling people to repent. It may mean telling people about Jesus. It may be helping people to see the difference Jesus makes in the lives of other people today.
