To mineralogist,
Peace be with you. Christ said to his disciples, "Go therefore, and make disciples of people of all the nations, baptizing them in the name of the Father, and of the Son and of the holy spirit, teaching them to observe all the things I have commanded you.." (Matthew 28:19, 20) Notice he didn't say "Go knocking on doors." In fact, he prohibited them from doing that. Luke 10:7 He tells them, "Go not from house to house."
They were sent out into a city or a village, and to 'search out who in there is deserving.' The Christ said, "No man can come to me unless the Father draws him." (John 6:44). The 'spirit' would tell the disciples who in that 'city' is deserving and that one would approach them and ask. The disciples, in turn would heal the sick, tell them the things they heard from God and be ministers to them. If they were bidded to "dine with certain ones," they would go and dine with them. The only time Jesus 'entered a house' was when he was INVITED to. Zaccheus, the Pharisee, Lazarus, Martha, Mary, etc. all invited him. So he stayed there until he leaved. Anytime "we" were invited, we would stay there until we leave. We are not to go 'knocking on doors' and disturbing the public. We are to go to those whom the holy spirit sends us and help them in any way we can, whether physically, spiritually, or mentally. This is what the Christ means. Not that we should be "ministered to" but that we should "minister to others" the things we have.
