This is what I learnt from the above topic the teaching of Bro Eli Soriano of blessed memory. Let look at the Bible verse mark 16 verse 15 that says:
[15]And he said unto them, Go ye into all the world, and preach the gospel to every creature.
There is no sin of going from one house to another house to preach the gospel of God but there is a ways to communicate to reach more people at a time.
Our God is a great God and He always do great things in our life. He can talk with anybody in spirit. Technology have made it easier for us that we can talk to people at ago. God bless his words.
