The following is what I understand from Brother Eli's video of which anyone can be part of by watching and responding:

Using the modern means of communication to propagate the gospel is a great idea, and preaching does not have to be done in a corner as Apostle Paul stated in Acts 26:26.

Brother Eli himself travelled to Areopacus, and stood on the same mount where Paul stood, calling on the men of Athens to hear the word of God.

The modern means of communication has opened the channel to preach the gospel to all nations. This is unlike the old fashioned door-to-door approach which is more tasking with little to show.

Isaiah 43:9 refers to the gathering of all nations, and letting all the people to be assembled. God wants all the nations to be gathered. The salvation of God is open to every people and nation.

Jesus also told his disciples in Mt. 28:20 to make disciples of all nations, baptizing them in the name of the Father, the Son and the Holy Spirit, and teaching them his commandments.
