Whole World for Jesus
It is clear that the Great Commission is to bring Jesus to the entire world:
Matthew 28:18-20 (ESV)
18 And Jesus came and said to them, “All authority in heaven and on earth has been given to me.
19 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,
20 teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.”
Every single Christian should would to participate in the Great Commission. Not because it is a command but because SOULS MATTER.
You may say how can it happen?
The Holy Spirit makes evangelism possible. Without the Holy Spirit, the Great Commission is only an impossible dream. But with the impetus and involvement of the Holy Spirit, preaching the Gospel to all creation is not just wishful thinking.
Every single Christian has the Holy Spirit living in them and thus able to share the Gospel of Jesus Christ. He is the only resource they ultimately need. (Of course it is helpful to know what the Bible teaches, to learn from others, etc.)
Many Christians do not witness because they lack boldness. What should be clear from reading the Acts of the Apostles in the Bible is those filled with the Holy Spirit, being baptized with the Holy Spirit, whatever term you what to use, walked in boldness at a minimum. There was also signs and wonders that accompanied their witnessing.
So do you want the Gospel to go out into the whole world. Do you want to have some part in this? Do you need boldness? Why not ask God to baptize you with His Holy Spirit? To overwhelm you with His presence and power.
